“17 Reviews” — wind turbine noise and human health

[Now 45 reviews! Go to wndfo.net/revs for just the non-government, non-industry reviews.]

In January 2012, Australian anti-tobacco/pro-wind public health activist Simon Chapman compiled a “Summary of main conclusions reached in 17 reviews of the research literature on wind farms and health”. His list, which not surprisingly ignores many reviews and commentaries that support health concern, and which misinterprets even these 17 to support his and the industry’s determination to dismiss health concerns, has since been used tirelessly (and tiresomely) as a rhetorical cudgel by the wind industry.

In December 2012, Wayne Gulden in Ontario examined Chapman’s “17 reviews”: He found that: 3 of the reviews didn’t even discuss wind turbines; only 4, maybe 5, were peer reviewed, including one of the reviews that didn’t mention wind turbines; only 1 was independent from pro-wind interests (but was not peer reviewed); and the majority based their conclusions on only 4 studies, added to which Gulden suggests a 5th, published after most of the reviews in Chapman’s list:

(Update, October 7, 2013: Do your own review:  Click here for access to 21 published studies (2003–2012) of health effects of industrial wind turbine noise.)

By using the “17 reviews” as a cudgel against its perceived enemies, the industry hopes nobody actually looks at them for themselves. The fact is, they express uncertainty more than anything and generally recognize the validity of and need for more study of the health effects of wind turbine noise. They certainly do not claim that there are no adverse health effects from wind turbines (because absence of evidence is not evidence of absence). Here are quotes from each of the 17 reviews that serve the opposite of Chapman’s aim (most of them by courtesy of Gulden’s summary, where links are provided):
  1. Massachusetts Department of Environmental Protection: Wind turbine health impact study: report of independent expert panel: “it is possible that noise from some wind turbines can cause sleep disruption” (critiques of the Mass. DEP review can be seen here, here, here, and here) (update: In June 2013, based on continuing collection of information Mass. DEP convened a Wind Turbine and Noise Technical Advisory Group to assess and regulate noise impacts)
  2. Oregon wind energy health impact assessment: “people who reported annoyance outdoors were more likely to report sleep interruption, feeling tense and stressed, and feeling irritable. Annoyance indoors was positively associated with sleep interruption.”
  3. Fiumicelli D: Windfarm noise dose-response: a literature review (Acoustics Bulletin): “uncertainty about human response to wind turbine noise”
  4. Bolin K et al: Infrasound and low frequency noise from wind turbines: exposure and health effects (Environmental Res Let): “statistically significant association between wind turbine noise and self-reported sleep disturbance”
  5. Knopper LD, Ollson CA: Health effects and wind turbines: a review of the literature (Environmental Health): “wind turbines can be a source of annoyance for some people”
  6. UK Health Protection Agency: Report on the health effects of infrasound: “Artificial sources of infrasound include ... wind turbines”
  7. Australia National Health and Medical Research Council: Wind turbines and health: a rapid review of the evidence: “any potential impact on humans can be minimised by following existing planning guidelines” (this is the only review that thus completely denies the problem [Simon Chapman himself, who is not a physician nor an acoustician, was one of the ‘peer reviewers’]; nevertheless, the same group, ie, the National Health and Medical Research Council [NHMRC] of Australia, stated regarding this “rapid review” that “relevant authorities should take a precautionary approach”, and their own study is ongoing).  Update, February 25, 2014: Chapman has added the NHMRC consultation draft report, Evidence on Wind Farms and Human Health, to his list. It concludes: “Further high quality research is needed.”
  8. King, A (Chief Medical Officer of Health, Ontario): The potential health impact of wind turbines: “sound measurements at residential areas around wind turbines and comparisons with sound levels around other rural and urban areas, to assess actual ambient noise levels prevalent in Ontario, is a key data gap that could be addressed. An assessment of noise levels around wind power developments and other residential environments, including monitoring for sound level compliance, is an important prerequisite to making an informed decision on whether epidemiological studies looking at health outcomes will be useful.”
  9. UK Health Protection Agency: Environmental noise and health in the UK: “noise from wind farms ... these are all subjects that are in need of study”
  10. Minnesota Department of Health, Environmental Health Division: Public health impacts of wind turbines: “Sleeplessness and headache are the most common health complaints and are highly correlated (but not perfectly correlated) with annoyance complaints.”
  11. Canadian Wind Energy Association: Addressing concerns with wind turbines and human health: “CanWEA is a non-profit trade association”
  12. Colby et al: Wind turbine sound and health effects: an expert panel review: “Prepared for: American Wind Energy Association and Canadian Wind Energy Association”
  13. Colby D, Chatham-Kent Public Health Unit: The health impact of wind turbines: a review of the current white, grey and published literature: precursor of the above
  14. US National Research Council: Impact of wind energy development on humans (in: Environmental impacts of wind-energy projects: “In the absence of extensive data, this report focuses mainly on appropriate methods for analysis and assessment and on recommended practices in the face of uncertainty. ... Low-frequency vibration and its effects on humans are not well understood. Sensitivity to such vibration resulting from wind-turbine noise is highly variable among humans. ... More needs to be understood regarding the effects of low-frequency noise on humans.”
  15. Jakobsen J: Infrasound emission from wind turbines (J Low Frequency Noise, Vibration and Active Control): “a simple assessment of the ‘normal’ wind turbine noise suggests a fair explanation of the adverse public reaction”
  16. Leventhall G: Low frequency noise and annoyance (Noise & Health): “Low frequency noise, the frequency range from about 10Hz to 200Hz, has been recognised as a special environmental noise problem, particularly to sensitive people in their homes. Conventional methods of assessing annoyance, typically based on A-weighted equivalent level, are inadequate for low frequency noise and lead to incorrect decisions by regulatory authorities. There have been a large number of laboratory measurements of annoyance by low frequency noise, each with different spectra and levels, making comparisons difficult, but the main conclusions are that annoyance of low frequencies increases rapidly with level. Additionally the A-weighted level underestimates the effects of low frequency noises.” Leventhall had also previously (2003) written a “Review of published research on low frequency noise and its effects” for the U.K. government, noting that “dBA underestimates annoyance for frequencies below about 200Hz. ... Table 5 shows very adverse effects from low frequency noise levels which are close to the threshold and which do not exceed A-weighted limits. ... Infrasound exposure is ubiquitous in modern life ... and as an emission from many artificial sources ... including wind turbines. ... There is no doubt that some humans exposed to infrasound experience abnormal ear, CNS, and resonance induced symptoms that are real and stressful.”
  17. Pedersen, E (Sweden Environmental Protection Agency): Noise annoyance from wind turbines: a review: “Noise from wind turbines is not at all as well studied as for instance noise from road traffic. As the number of studies is low no general conclusions could be drawn. However, ... annoyance from wind turbine noise: is to a degree correlated to noise exposure; occurs to a higher degree at low noise levels than noise annoyance from other sources of community noise such as traffic. ... Wind turbine noise: is, due to its characteristics, not easily masked by background noise; is particularly poorly masked by background noise at certain topographical conditions.”

Then there are reviews that Chapman chooses not to include, for example:

Senate inquiry into the social and economic impact of rural wind farms (2010), Australia: “The Committee: considers that the noise standards adopted by the states and territories for the planning and operation of rural wind farms should include appropriate measures to calculate the impact of low frequency noise and vibrations indoors at impacted dwellings; ... recommends that the Commonwealth Government initiate as a matter of priority thorough, adequately resourced epidemiological and laboratory studies of the possible effects of wind farms on human health; ... recommends that the National Acoustics Laboratories conduct a study and assessment of noise impacts of wind farms, including the impacts of infrasound; recommends that the draft National Wind Farm Development Guidelines be redrafted to include discussion of any adverse health effects and comments made by NHMRC regarding the revision of its 2010 public statement.”

Literature review 2013: association between wind turbine noise and human distress, by Ian Arra and Hazel Lynn: “All studies rejected the Null Hypothesis (no association between wind turbine noise and human distress). In other words, evidence of association was found (weak evidence: Level 4 and 5). No published peer-reviewed study showed no association. Three studies showed dose-response relationship. The studies are level 4 or 5 (a weak type of evidence). Nevertheless, [they] strongly warrant further research (multiple studies, multiple designs, investigating multiple hypothesis).” Update, May 24, 2014: Systematic review 2013: Association between wind turbines and human distress. Cureus 6(5):e183. “In this review, we have demonstrated the presence of reasonable evidence (Level Four and Five) that an association exists between wind turbines and distress in humans. The existence of a dose-response relationship (between distance from wind turbines and distress) and the consistency of association across studies found in the scientific literature argues for the credibility of this association.”

Wind farm noise and human perception: a review (April 2013), by Noise Measurement Services, Australia: “The hypothesis from this Review is that serious harm to health occurs when a susceptible individual is so beset by the noise in question that he or she suffers recurring sleep disturbance, anxiety and stress. Research for the Review suggests that 5% to 10% of the individuals living in the vicinity of a large wind farm will experience serious harm to their health. The observed markers for serious health effects are: wind farm noise level of LAeq 32 dB or more outside the residence; and wind farm noise is heard or is perceptible (felt) at levels above the individual’s threshold of hearing inside the home.”

(Update 2, October 3, 2013: “32 reviews”. Wind turbine noise, Christopher Hanning and Alun Evans, BMJ 2012;344:e1527 (Published 8 March 2012): “A large body of evidence now exists to suggest that wind turbines disturb sleep and impair health at distances and external noise levels that are permitted in most jurisdictions ... Sleep disturbance may be a particular problem in children, and it may have important implications for public health. ... Robust independent research into the health effects of existing wind farms is long overdue.”)

Update, May 7, 2013:  “19 reviews”?  Two more “official reviews” were issued in April that Chapman or his acolytes will no doubt add to his list: 1) Wind Farms, Sound and Health, by the Department of Health, Victoria, published in “Technical information” and “Community information” forms; and 2) Report on Health Impacts of Wind Turbines, prepared for the Scottish Government by Sabine von Hünerbein, Andy Moorhouse, Dani Fiumicelli, and David Baguley of the University of Salford, Manchester (“a rapid, desk based analysis of ... literature specified by the Scottish government, peer-reviewed original studies and recent peer-reviewed literature reviews”).

The Victorian Department of Health pamphlet concludes, “Wind farm sound, including low levels of low frequency sound, may be audible to nearby residents. Audible noise from any source, including windfarms, can cause annoyance, resulting in prolonged stress and other health effects.” It also insists, “There is no evidence that sound which is at inaudible levels can have a physiological effect on the human body. This is the case for sound at any frequency, including infrasound.” This clearly means evidence that they choose to consider, because there is indeed such evidence, and it is a growing area of research (see, e.g., the links here). The pamphlet also compares wind turbine infrasound favorably against one’s own heartbeat and breathing, but (ignoring the cited measurements being selective and simplistic) that may in fact be part of the problem as an external source forces itself on the body’s own physical rhythms. Update, May 28, 2013:  Wind Watch has posted two letters to the Victorian Department of Health pointing out shortcomings of their information sheets: 1) from Alec Salt and Jeffery Lichtenhan about the direct physiological effects of low-frequency noise; and 2) from Colin Hansen about the unique characteristics of wind turbine noise.

Von Hünerbein has produced government policy–affirming reports about wind turbine noise before, and this is only the latest. The tone of her conclusions makes her bias clear: in short, although there may well be problems, even to causing ill health, measures to prevent that would be too burdensome for the development of wind energy. “The review shows there to be evidence for annoyance due to WT noise. There is also some evidence for sleep disturbance which has found fairly wide, though not universal, acceptance. It should be noted that environmental noise from other sources such as road traffic and aircraft noise is a known causes of annoyance and sleep disturbance so to find these effects from WTs is not unexpected. Some authors label these effects as health effects and others do not. If low frequency noise and infrasound was an issue an as yet unproven method of human response would have to be involved. Universally agreed noise mitigation strategies have not been identified. Generally noise issues can be minimised by conservative noise limits. Set-back distances are also used internationally but have a number of disadvantages. The relevant [and much criticized] UK guideline document ETSU-R-97 has been derived from research on the response to noise and aims to provide a reasonable degree of protection to noise sensitive listeners; without unduly restricting the development of WT renewable energy resources.”

Update, May 23, 2013:  “20 reviews”!  At least here — Chapman is still at 19, having added the information sheets from the Victoria Department of Health and another government report: Wind Turbines and Health, by Patricia Fortin, Karen Rideout, Ray Copes, and Constance Bos of the National Collaborating Centre for Environmental Health at the British Columbia Centre for Disease Control, February 2013.

“The sound level associated with wind turbines at common residential setbacks ... may lead to annoyance and sleep disturbance. ... Sleep interruption has been associated with wind turbine sound among residents living less than 2.5 km from turbines, particularly when sound levels are above 45 dBA at night; however, some people report noise annoyance from wind turbines at outdoor sound levels below 40 dBA and at lower levels than other sources of environmental noise. When aerodynamic modulation (swishing sound) occurs, wind turbine sound may be perceived as more annoying than steady sound or “white noise.” ... [I]f the noise has an outdoor A-weighted level, which corrects measurements to the low-level frequency sensitivity of the human ear, of 40 dBA, there is a risk that some residents will be annoyed by low-frequency noise even indoors. A small increase in sound level at low frequency can result in a large increase in perceived loudness and may be difficult to ignore, even at relatively low sound pressure levels, increasing the potential for annoyance when there is a sizeable low frequency component. It is suggested that problems can be reduced with an outdoor limit of 35 dBA for large wind turbines.”

Update, May 24, 2013:  “24 reviews”.  Public health effects of siting and operating onshore wind turbines, Conseil Supérieur de la Sante, Belgium, publication no. 8738, 3 April 2013: “Modern wind turbines are unlikely to have any direct effects on health and well-being other than annoyance and possibly sleep disturbance. Both annoyance and disturbed sleep can, however, lead to undue stress, which may adversely affect the health and well-being of those concerned. ... It follows that the operation of wind turbines or wind farms may affect the quality of life (i.e. health and well-being), but in a complex fashion that depends on a variety of interrelated factors. ... [L]a nuisance attribuée au bruit du fonctionnement des éoliennes, tant en phase d’éveil que lors du sommeil, constitue un effet environnemental majeur sur la santé. [Annoyance attributed to the operation of wind turbines, while awake as much as during sleep, constitutes a major environmental health impact.] ... The noise levels due to the operation of wind turbines and wind farms near people’s homes should comply with the World Health Organisation (WHO) and WHO Europe guidelines for day-time and night-time noise exposure in order to avoid serious annoyance and (self-reported) sleep disturbance. This would lead to [outside] sound levels below 45 dB(A) during day-time and 40 dB(A) at night. ... Belgium should participate in or take the initiative for an international study on the possible specific impacts of wind turbine operation on the health and well-being of those living in their vicinity.”

Update, May 27, 2013:  “25 reviews”.  There are also older reviews, predating the work of Nina Pierpont and Sarah Laurie, the two physicians primarily attacked by wind advocates for “causing” health problems by documenting them, for example:

Eoliennes, sons et infrasons: Effets de l’éolien industriel sur la sante des hommes (Wind turbines, noise, and infrasound: effects of industrial wind turbines on human health), by Marjolaine Villey-Migraine, Université Paris II–Panthéon-Assas, December 2004: “Les aérogénérateurs émettent des infrasons, ceci n’est controversé par personne. ... Il nous paraît immoral de la part de cet organisme [Agence de l’Environnement et de la Maitrise de l’Energie] d’affirmer, sans référence aucune, que les infrasons émis par les éoliennes sont parfaitement inoffensifs, et d’autre part, de faire état de soi-disant “mesures”, alors qu’on ne peut prouver l’impact de infrasons des éoliennes sur l’homme que par des études épidémiologiques. ... Les sons et infrasons émis par les éoliennes ont un impact certain sur la santé de l’homme et peuvent gâcher la vie des gens. ... Les promoteurs éoliens ont la responsabilité de mettre en place les mesures adéquates pour diminuer les risques d’atteinte à la santé des riverains des éoliennes, en les éloignant des habitations non de 500 m comme ils le suggèrent dans leurs publications, mais à 1600 m en tenant compte de sons, et au minimum à 5 km en tenant compte des infrasons.” (“Wind turbines emit infrasound, this is not disputed by anyone. ... It seems to us immoral on the part of this organization [Agency of the Environment and Energy Management] to assert, without any reference, that infrasound emitted by wind turbines is perfectly harmless, and furthermore, to make claims of so-called “action,” but that we can not prove the impact of wind turbine infrasound on humans by epidemiological studies. ... Noise and infrasound emitted by wind turbines have a definite impact on the health of humans and can harm people’s lives. ... Wind developers have a responsibility to put in place adequate measures to reduce the risks of damage to the health of residents living near wind turbines by siting turbines no closer to homes than – not 500 m as suggested in their publications – but 1600 m considering audible noise and at least 5 km considering infrasound.”)

Le retentissement du fonctionnement des éoliennes sur la santé de l’homme (Repercussions of wind turbine operations on human health), by Claude-Henri Chouard, l’Académie nationale de médecine, France, March 2006: “Qu’il soit très intense, ou qu’il représente une pollution sonore plus modérée, le bruit est le grief le plus fréquemment formulé à propos des éoliennes. Il peut avoir un impact réel, et jusqu’ici méconnu, sur la santé de l’homme. ... [I]l serait souhaitable, par précaution, que soit suspendue la construction des éoliennes d’une puissance supérieure à 2,5 MW situées à moins de 1500 mètres des habitations.” (“Whether it is quite intense or it represents a more moderate noise pollution, noise is the complaint most frequently made concerning wind turbines. It can have a real impact, and so far disregarded, on human health. ... It would be desirable, as a precaution, to halt the construction of wind turbine facilities greater than 2.5 MW closer than 1500 meters from homes.”)

Location, location, location: An investigation into wind farms and noise, by The Noise Association, U.K., July 2006: “[W]ind farm noise generates many more complaints than equivalent levels of noise from most other sources, including road noise. ... [L]ow-frequency noise is much more disturbing indoors than outside ... Dr Geoff Leventhall agrees there are times when ‘A’ weighting is not entirely adequate: “Audible low-frequency noise does have annoying characteristics which are not shown in conventional environmental noise measures, such as A-weighting.” ... There has never been any dispute that wind turbines generate infrasound. ... Wind Farm noise, in common with noise generally, affects different people in different ways, but the evidence suggests there is rarely a problem for people living more than 1-1.5 miles from a turbine.”

(Update, October 24, 2013:  “33 reviews”. Infraschall von Windkraftanlagen als Gesundheitsgefahr (Infrasound from wind turbines as a health hazard), Erwin Quambusch and Martin Lauffer, ZFSH/SGB–Zeitschrift für die sozialrechtliche Praxis 08/2008: “Windkraftanlagen erzeugen unzweifelhaft Infraschall. Im Gegensatz zu den Äußerungen von Behörden und den den Anlagenbetreibern nahestehenden Institutionen, Infraschall sei “völlig harmlos”, verweist eine zunehmende Zahl von Wissenschaftlern auf die gesundheitliche Gefährlichkeit des Infraschalls. Die Gefahr stellt sich inzwischen als so hinreichend wahrscheinlich dar, dass an die Stelle der bisher gepflegten Ignoranz staatliche Maßnahmen der Gefahrenabwehr und der Gefahrenvorsorge treten müssen. Solange und soweit die Gesundheitsgefahren nicht durch technische oder ähnliche Vorkehrungen abgewehrt werden können, können Errichtung und Betrieb der Anlagen nur zulässig sein, wenn diese außerhalb der Sichtweite zu Wohngebieten liegen.” (“There is no doubt that wind turbines produce infrasound. In contrast to the pronouncements of the authorities, plant operators, and related institutions that infrasound is “completely harmless”, there are an increasing number of scientists noting the health risks of infrasound. The risk is sufficient that new regulations are required for prevention. As long as and to the extent that the health risks are not prevented by technical or similar guidelines, construction and operation of these plants should be allowed only if they are out of sight of residential areas.”)

Update, August 2, 2013:  “28 reviews”.  Report on the Health Impacts of Wind Farms, Sarah Taylor, Director of Public Health & Planning, National Health Service Shetland, 15th July 2013: “It is generally accepted that the primary effect of low frequency noise on people is annoyance. Annoyance is recognised as a critical health effect, and is associated in some people with stress, sleep disturbance, and interference with daily living. There is an increasing body of evidence that noise levels associated with wind farms cause annoyance, in a dose-related response. ... A range of symptoms are attributed to the noise of wind turbines in people living close to them, which are those associated with general environmental noise exposure, and are often also described as stress symptoms. They include headache, irritability, difficulty concentrating, fatigue, dizziness, anxiety, and sleep disturbance, and are often described in relation to annoyance. ... [I]t is recognised that low level noise from wind turbines is more often found to cause annoyance than similar levels from other sources. Some consider that the common cause of complaints from wind farms is not associated with low frequency noise but with the audible modulation of the aerodynamic noise, especially at night. There is also evidence that some people perceive the low frequency noise components of wind turbine noise, and that these are more significant at night and with large wind turbines. ... Regardless of whether the perceived impacts of noise from wind farms are physiological or psychological in nature, they are considered to cause adverse health effects through sleep disturbance, reducing the quality of life and as a source of annoyance which sometimes leads to stress related symptoms. ... Conclusions: Wind turbines are known to cause a number of effects that have an impact on health: risks from ice throw and structural failures that are minimised by appropriate setback distances; noise and shadow flicker that are sources of annoyance, sleep disturbance and symptoms of stress in some people. Current mitigations do not entirely deal with the annoyance caused by wind farms, the results of which are a cause of distress and related ill health for a number of people living in the vicinity.”

Update, September 26, 2013:  “29 reviews”.  Kirjallisuuskatsaus – Tuulivoiman terveysvaikutukset (Literature review – Health effects of wind power), Saara Huttunen, Johanna Kohl, and Nina Wessberg, Valtion Teknillinen Tutkimuskeskus (Technical Research Centre of Finland) for Suomen Tuulivoimayhdistys (Finnish Wind Power Association), 16.8.2013: This industry report concludes that all adverse health effects are merely a problem of public relations.

Update, October 3, 2013:  “30 reviews”.  Health impact of wind farms, Donata Kurpas, Bozena Mroczek, Beata Karakiewicz, Krzysztof Kassolik, and Waldemar Andrzejewski, Annals of Agricultural and Environmental Medicine 2013, Vol 20, No 3, 595–605: “Short description of state of the art: The nuisance caused by wind turbines is stereotypically linked with the noise that they produce. Nevertheless, the visual aspect of wind farms, opinions about them, and sensitivity to sound seem to be of the greater importance. ... Health effects are more probably associated with some environmental factors leading to annoyance or frustration. All types of studies share the same conclusion: wind turbines can provoke annoyance. ... The influence of wind turbines on human emotional and physical health is a relatively new field of research. Further analyses of these issues are justified, especially because none of the studies published in peer-reviewed journals so far meet the criteria for cohort or case-control studies. ... The authors did not analyse coherent publications or website documents (study by M. Alves-Pereira and N.C. Branco and the study by N. Pierpont).” [The authors also missed the Nissenbaum 2012 paper in Noise & Health, which appeared after their submission. And they assert that noise from wind turbines cause only subjective effects, despite the evidence under review of interference with, e.g., sleep, and physiological effects.] “The authors are involved in community public consultations with the advocates of new projects” [rather a major conflict of interest to be mentioned only in passing].

Regulations for construction of wind turbines should be revised, taking this fact into account.”)

Industrial Wind Turbines, Human Variability, and Adverse Health Effects, Michael A. Nissenbaum, New England College of Occupational and Environmental Medicine Reporter, Volume 2 Issue 38 Fall 2013: “In summary, in many IWT projects, the preconstruction sound modeling has underestimated the eventual real world sound levels those turbine projects eventually produce. When coupled with the underappreciated human physiological responses to the type of noise large turbines produce (adverse sleep and mental health effects), this has had real world consequences for those living near them. The relationship of noise to sleep disturbances is established. The biological plausibility of sleep disturbances resulting in ill health is settled science. Chronic noise exposure leads to chronic sleep disturbance in many of those exposed, often resulting in ill health. Observed adverse human effects must trump preconstruction sound modeling; changes in practice must occur when there are errors. It’s all about distance when siting decisions are made.”

In the reviewed studies the authors found that annoyance plays a large role in people’s perception of wind turbines and additional research is warranted” (“About the Cover”). “Although limited, research has demonstrated that LFS can elicit adverse physical health effects, such as vibration or fatigue, as well as an annoyance or unpleasantness response. ... [T]he association and particular pathway between LFS specifically generated from wind turbines, annoyance, and adverse physical health effects have yet to be fully characterized. Hence, additional epidemiological research studies are warranted” (poster presentation, Jennifer Roberts, 4 July 2012, 7th International Conference on the Science of Exposure Assessment).

Update, June 19, 2014:  “37 reviews”.  Wind turbines and human health, Loren Knopper, Christopher Ollson, et al., Frontiers in Public Health 2014;2:63: “Setbacks should be sound-based rather than distance-based alone. Preference should be given to sound emissions of ≤40 dB(A) for non-participating receptors, measured outside, at a dwelling, and not including ambient noise. ... Post construction monitoring should be common place to ensure modeled sound levels are within required noise limits. If sound emissions from wind projects is in the 40–45 dB(A) range for non-participating receptors, we suggest community consultation and community support. Setbacks that permit sound levels >45 dB(A) (wind turbine noise only; not including ambient noise) for non-participating receptors directly outside a dwelling are not supported due to possible direct effects from audibility and possible levels of annoyance above background. When ambient noise is taken into account, wind turbine noise can be >45 dB(A), but a combined wind turbine–ambient noise should not exceed >55 dB(A) for non-participating and participating receptors. Our suggested upper limit is based on WHO conclusions that noise above 55 dB(A) is ‘considered increasingly dangerous for public health,’ is when ‘adverse health effects occur frequently, a sizeable proportion of the population is highly annoyed and sleep-disturbed’ and ‘cardiovascular effects become the major public health concern, which are likely to be less dependent on the nature of the noise.’”

A review of studies related to general low-frequency noise annoyance shows there are similarities with annoyance studies involving wind turbine noise. ... noise levels may comply with existing environmental noise guidelines based on the dB(A) scale yet still cause annoyance due to the uniqueness of low-frequency noise problems. However, there is very little information (level, spectral balance, temporal qualities, etc) regarding low-frequency noise in people’s homes affected by wind turbines. ... Thus more research is needed in understanding the fundamental aspects of wind turbine low-frequency noise generation, propagation and perception.”

There seems to be a tolerable limit of around LAeq of 35 dB. Logically, accepting higher limits in legislations may lead to increased numbers of annoyed subjects. It therefore seems reasonable to conclude that a cautious approach is needed when planning future wind farms. Furthermore, there is an indication that noise annoyance and sleep disturbance are related and that disturbed sleep potentially can lead to adverse health effects. These conclusions are, however, affected by a potential risk for selection and information bias even in the larger cross-sectional studies providing the current best evidence. The evidence for adverse health effects other than sleep disturbance is primarily supported by case-series reports which certainly may be affected by various sources of bias. Larger cross-sectional surveys have so far been unable to document a relationship between various symptoms such as tinnitus, hearing loss, vertigo, headache and exposure to wind turbine noise. One limitation causing this could be that most studies so far have only measured LAeq or Lden. An additional focus on the measurement of low-frequency sound exposure as well as a more thorough characterisation of the amplitude modulated sound and the relationship between objective and subjective health parameters could lead to different conclusions in the future. Finally, in regards to the objective measurement of health-related disorders in relation to wind turbine noise, it would be valuable to demonstrate if such health-related outcomes fluctuate depending on exposure to wind turbine noise.”

Also:  “There is clear evidence of an annoyance or irritability caused by the acoustic signal from wind turbines that appears to be greater compared to other equivalent-level environmental noise such as airport or road traffic noise. In this regard, wind turbine noise is unique in having low-frequency signal components including infrasound (below 20 Hz). The sounds that are audible have a distinct amplitude modulation component, generally described as a “swish” or “thump”. This rhythmic characteristic makes the noise difficult to ignore or to adapt to, and its enhanced perception compared to un-modulated noise appears to contribute to its increased annoyance factor. Biological health issues can arise when the irritability and annoyance leads to sleep disturbance and stress.” —On the biological plausibility of Wind Turbine Syndrome, Robert Harrison, International Journal of Environmental Health Research, 2015, Vol. 25, No. 5, 463–468.

Wind Turbine Syndrome

Wind turbine syndrome (WTS) is a cluster of clinical symptoms first formally identified by British physician Amanda Harry, MD, and subsequently given the name Wind Turbine Syndrome and a pathophysiological explanation by New York State behavioral pediatrician Nina Pierpont, MD, PhD.

WTS refers to the discrete constellation of symptoms that some -- not all -- people experience when living near wind turbines, symptoms which Pierpont and other clinicians maintain are caused chiefly by turbine low-frequency noise and vibration and shadow flicker affecting the body's various balance organs, including the utricle and saccule (vestibular organs) of the inner ear. According to Pierpont, people at notable risk for WTS are those with migraine disorder and a history of balance and motion sensitivity (such as car-sickness and sea-sickness).

Both Harry and Pierpont have based their research on clinical case series (defined, in medicine, as a descriptive account of a group of individuals with the same new medical conditions), and both have called for large-scale government-sponsored epidemiological studies to definitively establish WTS as a full-blown disease state. Until that happens, WTS remains, clinically, merely a syndrome.

Symptoms

Pierpont has identified the following cluster of symptoms among many people living near wind turbines. In Wind Turbine Syndrome: A Report on a Natural Experiment (Santa Fe, NM: K-Selected Books, in press) she explains how these seemingly disparate symptoms result from turbine low frequency noise scrambling the body's balance, motion, and position sensors.
  1. sleep disturbance
  2. headache
  3. tinnitus (pronounced "tinn-uh-tus": ringing or buzzing in the ears)
  4. ear pressure
  5. dizziness (a general term that includes vertigo, lightheadedness, sensation of almost fainting, etc.)
  6. vertigo (clinically, vertigo refers to the sensation of spinning, or the room moving)
  7. nausea
  8. visual blurring
  9. tachycardia (rapid heart rate)
  10. irritability
  11. problems with concentration and memory
  12. panic episodes associated with sensations of internal pulsation or quivering, which arise while awake or asleep
Case reports

British physician Dr. Amanda Harry, in a February 2007 article titled "Wind Turbines, Noise and Health" [1], wrote of 39 people, including residents of New Zealand and Australia, who suffered from the sounds emitted by wind turbines.

Pierpont interviewed 10 families living near large (1.5-3 MW) wind turbines, for a total of 38 people from infants to age 75. People in these families had noticed that they developed new symptoms after the turbines started turning near their homes. They noticed that when they went away, the symptoms went away, and when they came back the symptoms returned. Eight of the 10 families eventually moved away from their homes because they were so troubled by the symptoms.

Dr. Michael A. Nissenbaum, a radiologist at the Northern Maine Medical Center, conducted interviews with 15 people living near the industrial wind energy facility in Mars Hill, Maine. The purpose of the interviews was to investigate and record the health effects on those living within 3,500 feet of industrial-scale turbines.

On March 25, 2009, Dr. Nissenbaum presented his preliminary findings before the Maine Medical Association. The data, which he characterized as alarming, suggest the residents are experiencing serious health problems related to shadow flicker and noise emissions from the turbines near their homes. The onset of symptoms, including sleep disturbance, headaches, dizziness, weight changes, possible increases in blood pressure, as well as increased prescription medication use, all appeared to coincide with the time when the turbines were first turned on (December 2006).[2]

On April 22, 2009, Dr. Robert McMurtry, former Dean of Medicine of the University of Western Ontario, released a survey conducted on the various wind facilities in Ontario. Of the 76 respondents in the community-based self-survey, 53 people living near different wind power plants reported that industrial wind turbines were having a significant negative impact on their lives. The adverse effects ranged from headaches and sleep disturbance to tinnitus (ringing in the ear) and depression.[3]

In Japan, more than 70 people living near wind turbines have reported ill health. They include residents in Ikata, Ehime Prefecture; Higashi-Izu, Shizuoka Prefecture; Toyohashi, Aichi Prefecture; and Minami-Awaji, Hyogo Prefecture. The Japanese Ministry of the Environment is now studying international data showing a potential link between wind turbines and health problems in surrounding areas to determine a plan of action for Japan. It has also started measuring low-frequency sounds around some wind farms.[4]

McMurtry is the founding Assistant Deputy Minister of the Population and Public Health Branch of Health Canada.
There are as yet no other reports in published clinical literature linking wind turbines to this set of symptoms. Residents of the U.K., however, presented their experience at the Second International Wind Turbine Noise Conference in Lyon, France, September 20-21, 2007.[5] And researchers in Portugal reported at the same conference that the conditions for Vibroacoustic Disease, in which low-frequency vibrations affect heart and lung tissues, were found in homes near wind energy facilities.[6]

Wind Turbine Syndrome, clarifies Pierpont, is not the same as Vibroacoustic Disease. The proposed mechanisms are different, and the noise amplitudes are probably different as well.

Wind Turbine Syndrome, according to Pierpont, is essentially low-frequency noise or vibration tricking the body's balance system into thinking it's moving. The process is mediated by the vestibular system -- in other words, by disturbed sensory input to eyes, inner ears, and stretch and pressure receptors in a variety of body locations. These feed back neurologically onto a person's sense of position and motion in space, which is in turn connected in multiple ways to brain functions as disparate as spatial memory and anxiety. New discoveries about the extreme noise/vibration sensitivity of the vestibular system of the human inner ear were published in Neuroscience Letters in 2008.[7]

Several lines of evidence suggest that the amplitude (power or intensity) of low-frequency noise and vibration needed to create these effects may be even lower than the auditory threshold at the same low frequencies. In othr words, it appears that even low-frequency noise or vibration too weak to hear can still stimulate the human vestibular system, opening the door for the symptoms that Pierpont has called Wind Turbine Syndrome. There is now direct experimental evidence of such vestibular sensitivity in normal humans.

Vibroacoustic Disease, on the other hand, is hypothesized to be caused by direct tissue damage to a variety of organs, creating thickening of supporting structures and other pathological changes. The suspected agent is high-amplitude (high power or intensity) low-frequency noise. Given Pierpont's research protocol, her study is unable to demonstrate whether wind turbine exposure causes the types of pathologies found in Vibroacoustic Disease, although there are similarities that may be worthy of further clinical investigation, especially regarding asthma and lower respiratory infections.

Against this growing evidence, the wind industry insists that no problem exists or that it is so rare as to be of little consequence. The Canadian Wind Energy Association, for example, cites a set of articles in the June 2006 issue of Canadian Acoustician as refutation of serious health effects from wind turbine noise. Besides the fact that they are not medical articles, they do not conclude that there is no evidence of health problems.[8] Although the wind industry denies that wind turbine noise is intrusive, let alone a health problem, it also fights against noise regulations that would ensure that to be the case.

In the United States, George Kamperman, INCE (Institute of Noise Control Engineering) Board Certified noise control engineer, and Rick James, INCE Full Member, have documented significantly increased levels and the unique character of noise from industrial-sized wind turbines. To ensure the World Health Organization recommendation of no more than 30 dB(A) inside a bedroom and that low-frequency noise be limited, they recommend that large wind turbines be sited at least 2 kilometers from homes.[9] Similarly, the Noise Association of the U.K. and the French Academy of Medicine recommend a distance of 1 mile or 1.5 kilometers, respectively.[10][11]

This is still an emerging phenomenon, but the evidence is clearly accumulating in support of Dr. Pierpont and others' observations of a clear clinical pattern of ill effects caused by large wind turbines.

Reviews of wind turbines’ effects on human health

Elsewhere on this blog, there is an inclusive list of reviews of the literature concerning human health and the noise from industrial wind turbines. It was compiled to provide a more complete list than the highly selective one presented by Simon Chapman of the University of Sydney that is often cited by wind power promoters. It also showed that while Chapman presented the reviews as reason to dismiss health concerns, most of them actually note the limited number and power of studies but that the evidence justifies further investigation and caution.

Most of the reviews, however, are government reports: nine of Chapman’s original 17, all of the three he later added, and five of the additional reviews listed earlier on this blog. Furthermore, of Chapman’s list, four are irrelevant (three not about wind turbines and one a press release about one of the other reviews), two are industry reports, and two are just rehashes of an earlier review. Only three of the reviews he originally listed merit attention:

Vetting these eleven, we find that: Dani Fiumicelli is Technical Director (Head of Noise and Vibration) of Temple Group, a development consultancy in the U.K., and is an author of a 2013 report for the Scottish government to deny concerns of health effects; Loren Knopper is Senior Scientist and Christopher Ollson is Vice President for Strategic Development of Intrinsik, an environment and health consultancy in Ontario, and in their paper they disclose that they “have worked with wind power companies”, that Ollson “has acted as an expert witness for wind power companies during a number of legal hearings”, and that all of the authors of their 2014 review are also disclosed to be employees of Intrinsik: “the authors work for a consulting firm and have worked with wind power companies”; in 2015 the Canadian Wind Energy Association honored Knopper and Ollson with their R. J. Templin Award for “results that have served to significantly advance the wind energy industry in Canada”; Mark Roberts is Principal Scientist of Exponent, an engineering and scientific consulting firm involved in wind energy development; and Kurpas et al. mention in passing towards the end of their paper that they “are involved in community public consultations with the advocates of new projects”. These potential conflicts are noted in the following quotes (ordered by date).

Villey-Migraine: “Wind turbines emit infrasound, this is not disputed by anyone. ... It seems to us immoral on the part of this organization [Agency of the Environment and Energy Management] to assert, without any reference, that infrasound emitted by wind turbines is perfectly harmless, and furthermore, to make claims of so-called ‘action,’ but that we can not prove the impact of wind turbine infrasound on humans by epidemiological studies. ... Noise and infrasound emitted by wind turbines have a definite impact on the health of humans and can harm people’s lives. ... Wind developers have a responsibility to put in place adequate measures to reduce the risks of damage to the health of residents living near wind turbines by siting turbines no closer to homes than – not 500 m as suggested in their publications – but 1600 m considering audible noise and at least 5 km considering infrasound.” [translated]

Chouard: “Whether it is quite intense or it represents a more moderate noise pollution, noise is the complaint most frequently made concerning wind turbines. It can have a real impact, and so far disregarded, on human health. ... It would be desirable, as a precaution, to halt the construction of wind turbine facilities greater than 2.5 MW closer than 1500 meters from homes.” [translated]

NRC: “In the absence of extensive data, this report focuses mainly on appropriate methods for analysis and assessment and on recommended practices in the face of uncertainty. ... Low-frequency vibration and its effects on humans are not well understood. Sensitivity to such vibration resulting from wind-turbine noise is highly variable among humans. ... More needs to be understood regarding the effects of low-frequency noise on humans.”

Quambusch & Lauffer: “There is no doubt that wind turbines produce infrasound. In contrast to the pronouncements of the authorities, plant operators, and related institutions that infrasound is "completely harmless", there are an increasing number of scientists noting the health risks of infrasound. The risk is sufficient that new regulations are required for prevention. As long as and to the extent that the health risks are not prevented by technical or similar guidelines, construction and operation of these plants should be allowed only if they are out of sight of residential areas.” [translated]

Knopper &: Ollson [industry consultants, non-medical]: “wind turbines can be a source of annoyance for some people”

Fiumicelli [industry consultant, non-medical]: “uncertainty about human response to wind turbine noise”

James [acoustician, non-medical]: “There is sufficient research and history to link the sensitivity of some people to inaudible amplitude-modulated infra and low-frequency noise to the type of symptoms described by those living near industrial wind turbines.”

Hanning & Evans: “A large body of evidence now exists to suggest that wind turbines disturb sleep and impair health at distances and external noise levels that are permitted in most jurisdictions ... Sleep disturbance may be a particular problem in children, and it may have important implications for public health. ... Robust independent research into the health effects of existing wind farms is long overdue.”)

Farboud et al.: “There is some evidence of symptoms in patients exposed to wind turbine noise. The effects of infrasound require further investigation.”

Doolan: “Low-frequency noise levels from wind turbines may exceed audibility thresholds and thus it is possible that they are correlated with annoyance. A review of studies related to general low-frequency noise annoyance shows there are similarities with annoyance studies involving wind turbine noise. ... noise levels may comply with existing environmental noise guidelines based on the dB(A) scale yet still cause annoyance due to the uniqueness of low-frequency noise problems. However, there is very little information (level, spectral balance, temporal qualities, etc) regarding low-frequency noise in people’s homes affected by wind turbines. ... Thus more research is needed in understanding the fundamental aspects of wind turbine low-frequency noise generation, propagation and perception.”

Roberts & Roberts [industry consultants]: “The answer to the question of whether or not exposure to wind turbine sound is a human health risk is still under review and warrants further research. Although limited, research has demonstrated that LFS [low-frequency sound] can elicit adverse physical health effects, such as vibration or fatigue, as well as an annoyance or unpleasantness response. The current research on exposure to wind turbine sound and the mere presence of wind turbines have also demonstrated a significant annoyance response among study participants. But the association and particular pathway between LFS specifically generated from wind turbines, annoyance, and adverse physical health effects have yet to be fully characterized.” [These authors also ignore the Nissenbaum et al. study in Noise & Health.]

Kurpas et al. [industry consultants]: “Short description of state of the art: The nuisance caused by wind turbines is stereotypically linked with the noise that they produce. Nevertheless, the visual aspect of wind farms, opinions about them, and sensitivity to sound seem to be of the greater importance. ... Health effects are more probably associated with some environmental factors leading to annoyance or frustration. All types of studies share the same conclusion: wind turbines can provoke annoyance. ... The influence of wind turbines on human emotional and physical health is a relatively new field of research. Further analyses of these issues are justified, especially because none of the studies published in peer-reviewed journals so far meet the criteria for cohort or case-control studies. ... The authors did not analyse coherent publications or website documents (study by M. Alves-Pereira and N.C. Branco and the study by N. Pierpont).” [The authors also missed the Nissenbaum 2012 paper in Noise & Health, which appeared after their submission. And they assert that noise from wind turbines cause only subjective effects, despite the evidence under review of interference with, e.g., sleep, and physiological effects.]

Enbom & Malcus Enbom: “Infrasound from wind turbines affects the inner ear and is a potential health risk for people with migraine or other type of central sentitisation. Regulations for construction of wind turbines should be revised, taking this fact into account.” [translated]

Nissenbaum: “In summary, in many IWT projects, the preconstruction sound modeling has underestimated the eventual real world sound levels those turbine projects eventually produce. When coupled with the underappreciated human physiological responses to the type of noise large turbines produce (adverse sleep and mental health effects), this has had real world consequences for those living near them. The relationship of noise to sleep disturbances is established. The biological plausibility of sleep disturbances resulting in ill health is settled science. Chronic noise exposure leads to chronic sleep disturbance in many of those exposed, often resulting in ill health. Observed adverse human effects must trump preconstruction sound modeling; changes in practice must occur when there are errors. It’s all about distance when siting decisions are made.”

Arra et al.: “In this review, we have demonstrated the presence of reasonable evidence (Level Four and Five) that an association exists between wind turbines and distress in humans. The existence of a dose-response relationship (between distance from wind turbines and distress) and the consistency of association across studies found in the scientific literature argues for the credibility of this association.”

Knopper, Ollson, et al. [industry consultants, non-medical]: “Setbacks should be sound-based rather than distance-based alone. Preference should be given to sound emissions of ≤40 dB(A) for non-participating receptors, measured outside, at a dwelling, and not including ambient noise. ... Post construction monitoring should be common place to ensure modeled sound levels are within required noise limits. If sound emissions from wind projects is in the 40–45 dB(A) range for non-participating receptors, we suggest community consultation and community support. Setbacks that permit sound levels >45 dB(A) (wind turbine noise only; not including ambient noise) for non-participating receptors directly outside a dwelling are not supported due to possible direct effects from audibility and possible levels of annoyance above background. When ambient noise is taken into account, wind turbine noise can be >45 dB(A), but a combined wind turbine–ambient noise should not exceed >55 dB(A) for non-participating and participating receptors. Our suggested upper limit is based on WHO conclusions that noise above 55 dB(A) is ‘considered increasingly dangerous for public health,’ is when ‘adverse health effects occur frequently, a sizeable proportion of the population is highly annoyed and sleep-disturbed’ and ‘cardiovascular effects become the major public health concern, which are likely to be less dependent on the nature of the noise.’”

Schmidt and Klokker: “At present it seems reasonable to conclude that noise from wind turbines increases the risk of annoyance and disturbed sleep in exposed subjects in a dose-response relationship. There seems to be a tolerable limit of around LAeq of 35 dB. Logically, accepting higher limits in legislations may lead to increased numbers of annoyed subjects. It therefore seems reasonable to conclude that a cautious approach is needed when planning future wind farms. Furthermore, there is an indication that noise annoyance and sleep disturbance are related and that disturbed sleep potentially can lead to adverse health effects. These conclusions are, however, affected by a potential risk for selection and information bias even in the larger cross-sectional studies providing the current best evidence. The evidence for adverse health effects other than sleep disturbance is primarily supported by case-series reports which certainly may be affected by various sources of bias. Larger cross-sectional surveys have so far been unable to document a relationship between various symptoms such as tinnitus, hearing loss, vertigo, headache and exposure to wind turbine noise. One limitation causing this could be that most studies so far have only measured LAeq or Lden. An additional focus on the measurement of low-frequency sound exposure as well as a more thorough characterisation of the amplitude modulated sound and the relationship between objective and subjective health parameters could lead to different conclusions in the future. Finally, in regards to the objective measurement of health-related disorders in relation to wind turbine noise, it would be valuable to demonstrate if such health-related outcomes fluctuate depending on exposure to wind turbine noise.”

Tran Ba Huy: “[L]e caractère intermittent, aléatoire, imprévisible, envahissant du bruit généré par la rotation des pales, survenant lorsque le vent se lève, variant avec son intensité, interdisant toute habituation, peut indubitablement perturber l’état psychologique de ceux qui y sont exposés. Ce sont notamment les modulations d’amplitudes causées par le passage des pales devant le mât qui sont dénoncées comme particulièrement dérangeantes.” [The intermittent, random, unpredictable, invasive character of the noise generated by the rotation of the blades, arising when the wind rises and varying along with its intensity, preventing habituation, can undoubtedly disturb the psychological state of those who are exposed to it. These include amplitude modulation caused by the passage of the blades in front of the mast, which is noted as particularly disturbing.] “[L]e groupe de travail recommande: ... de revenir pour ce qui concerne leur bruit (et tout en laissant les éoliennes sous le régime des Installations Classées pour le Protection de l’Environnement) au décret du 31 août 2006 relatif à la lutte contre les bruits du voisinage (relevant du code de Santé publique et non de celui de l’Environnement), ramenant le seuil de déclenchement des mesures d’émergence à 30 dB A à l’extérieur des habitations et à 25 à l’intérieur.” [The working group recommends returning to the decree of 31 August 2006 concerning the fight against neighborhood noise, reducing the the threshold for emergency measures to [ambient levels] 30 dBA outside residences and 25 dBA inside [limiting wind turbine noise to +5 dBA in daytime (7am–10pm) and +3 dBA at night (10pm–7am)].]

Also:  “There is clear evidence of an annoyance or irritability caused by the acoustic signal from wind turbines that appears to be greater compared to other equivalent-level environmental noise such as airport or road traffic noise. In this regard, wind turbine noise is unique in having low-frequency signal components including infrasound (below 20 Hz). The sounds that are audible have a distinct amplitude modulation component, generally described as a “swish” or “thump”. This rhythmic characteristic makes the noise difficult to ignore or to adapt to, and its enhanced perception compared to un-modulated noise appears to contribute to its increased annoyance factor. Biological health issues can arise when the irritability and annoyance leads to sleep disturbance and stress.” —Robert Harrison: On the biological plausibility of Wind Turbine Syndrome.

See no evil, hear no evil, nocebo

Can expectations produce symptoms from infrasound associated with wind turbines?
Fiona Crichton, George Dodd, Gian Schmid, Greg Gamble, and Keith J. Petrie, University of Auckland, New Zealand
Health Psychology, March 2013, doi:10.1037/a0031760 [update: republished online November 25, 2013. The Power of Positive and Negative Expectations to Influence Reported Symptoms and Mood During Exposure to Wind Farm Sound.]

First paragraph:  Harnessing wind energy is a critical component of long-term strategies for securing sustainable power supply in countries throughout the world, with the potential to help address global climate change. However, recent opposition to wind farms has seen a substantial increase in rejection rates for new wind farm developments, which threatens the achievement of renewable energy targets. Much of the opposition to wind farms stems from the belief that the infrasound produced by wind turbines causes health complaints in nearby residents. Although there is no empirical support for claims that infrasound generated by wind turbines could trigger adverse health effects, there has been a lack of other plausible mechanisms that could explain the experience of nonspecific symptoms reported by some people living in the vicinity of wind turbines. In this study we investigate whether exposure to information that creates negative expectations about symptoms from infrasound could be a possible explanation for this relationship.

Spatio-temporal differences in the history of health and noise complaints about Australian wind farms: evidence for the psychogenic, “communicated disease” hypothesis
Simon Chapman, Professor of Public Health, Alexis St George, Research Fellow, Karen Waller, and Vince Cakic, Sydney School of Public Health, University of Sydney, Australia
March 2013, unpublished [update: published online October 16, 2013. The Pattern of Complaints about Australian Wind Farms Does Not Match the Establishment and Distribution of Turbines: Support for the Psychogenic, ‘Communicated Disease’ Hypothesis. PLoS ONE 8(10): e76584. doi:10.1371/journal.pone.0076584]

Abstract (background, objectives, and conclusions):  With often florid allegations about health problems arising from wind turbine exposure now widespread in parts of rural Australia and on the internet, nocebo effects potentially confound any future investigation of turbine health impact. Historical audits of health complaints across periods when such claims were rare are therefore important. We test 4 hypotheses relevant to psychogenic explanations of the variable timing and distribution of health and noise complaints about wind farms in Australia. ... In view of scientific consensus that the evidence for wind turbine noise and infrasound causing health problems is poor, the reported spatio-temporal variations in complaints are consistent with psychogenic hypotheses that health problems arising are “communicated diseases” with nocebo effects likely to play an important role in the aetiology of complaints.

[[[[ || ]]]]

The bias of both of these papers is glaring. The Crichton paper seems more worried about wind development targets than about human health, and Chapman expresses his long established contempt and mockery of people adversely affected by wind development with the phrase "often florid allegations".

Both papers disingenuously claim that there is no scientific support for the claim that infrasound can have physiological effects. In fact, there is, and mechanisms for such effects are currently being elucidated (see, eg, Responses of the ear to infrasound and wind turbines, Low-frequency noise: a biophysical phenomenon, Infrasound: your ears “hear” it but they don’t tell your brain, Owen Black affidavit re: wind turbine syndrome, and the work of Mariana Alves-Pereira and Nuno Castelo Branco in Portugal: Vibroacoustic disease, Vibroacoustic disease: biological effects of infrasound and low-frequency noise explained by mechanotransduction cellular signalling, Industrial wind turbines, infrasound and vibro-acoustic disease (VAD), In-home wind turbine noise is conducive to vibroacoustic disease). [Update: see bibliography of PubMed-indexed studies at www.aweo.org/infrasound.html.] Both papers thus set out only to prove that "hysteria" is the cause, seeing no reason to test that hypothesis against the evidence for physical causes which they simply ignore.

Nor do they seem to consider the barrage of "positive" information that has accompanied the buildup of wind power. Related to this, they fail to consider the possibility (never mind the many reports) that people with a favorable view of wind development become adversely affected after a nearby facility began operation.

For these reasons, Chapman's paper is simply a joke. There is not even a pretense of testing his hypothesis, only a laughable effort to demonstrate it.

The Crichton paper at least pretends to set up a controlled experiment. Unfortunately, since the researchers ignore the work of acousticians who have measured infrasound from wind farms, they don't come close to recreating the experience of actual wind turbine noise (as, e.g., explored in Development of experimental facility for testing human response to ILFN from wind turbines), let alone its reported effects over time. They thus end up only showing the effect of suggestibility in two different "sham" situations. No group was actually exposed to infrasound levels and patterns like those from wind turbines.

Finally, these researchers exploit the fact that this phenomenon is indeed new, and consequently not yet extensively investigated, having developed along with the relatively recent growth of wind power development closer to homes. Furthermore, as with all noise phenomena, not everyone is affected, and those that are, to different degrees. There has been no robust epidemiological study of the issue, so it is irresponsible as well as unethical to dismiss it out of hand. Neither of these papers betrays the slightest humanity towards the many people who are truly suffering, many of them forced out of their homes. Nor does either one express the slightest interest in actual study of the cases. Both papers seem instead to be attempts to run ahead of the continuing medical and acoustical research and declare the issue dead. But the science has already left them well behind.

Update:  Another recent paper following Chapman's lead:

Fright factors about wind turbines and health in Ontario newspapers before and after the Green Energy Act
Benjamin Deignan, Erin Harvey, and Laurie Hoffman-Goetz, University of Waterloo, Ontario
Health, Risk & Society, March 2013, doi:10.1080/13698575.2013.776015

Abstract:  In this article, we analyse coverage of the health effects of wind turbines in Ontario newspapers relative to the Green Energy Act using published risk communication fright factors. Our aim was to provide insights into the health risk information presented in newspapers serving Ontario communities where wind turbines are located. ... We conclude that Ontario newspapers contain fright factors in articles about wind turbines and health that may produce fear, concern and anxiety for readers.

According to the abstract, this paper did not make any attempt to correlate the "fright factors" with health complaints, nor did it compare coverage of health concerns (which would of course be "negative") with coverage of wind energy development in general (which I dare say is overwhelmingly "positive"). And again, there does not seem to be any interest in examining actual cases, only in establishing theoretical bases for ignoring them.

This one seems even sillier (or more chilling) than Chapman's exercise, in that it is raising alarm about language. Are they suggesting that the Government of Ontario censor news coverage as part of its support for wind development?

Update:  And another recent paper along the lines of Crichton/Petrie:

The influence of negative oriented personality traits on the effects of wind turbine noise
Jennifer Taylor, Carol Eastwick, Robin Wilson, and Claire Lawrence, University of Nottingham, U.K.
Personality and Individual Differences, February 2013, doi:10.1016/j.paid.2012.09.018

Abstract:  Concern about invisible environmental agents from new technologies, such as radiation, radio-waves, and odours, have been shown to act as a trigger for reports of ill health. However, recently, it has been suggested that wind turbines – an archetypal green technology, are a new culprit in explanations of medically unexplained non-specific symptoms (NSS): the so-called Wind Turbine Syndrome (Pierpont, 2009). The current study assesses the effect of negative orientated personality (NOP) traits (Neuroticism, Negative Affectivity and Frustration Intolerance) on the relationship between both actual and perceived noise on NSS. All households near ten small and micro wind turbines in two UK cities completed measures of perceived turbine noise, Neuroticism, Negative Affectivity, Frustration Intolerance, attitude to wind turbines, and NSS (response N = 138). Actual turbine noise level for each household was also calculated. There was no evidence for the effect of calculated actual noise on NSS. The relationship between perceived noise and NSS was only found for individuals high in NOP traits[, suggesting] the key role of individual differences in the link between perceived (but not actual) environmental characteristics and symptom reporting.

According to the abstract, high NOP traits are correlated only with general health complaints, as would be expected, not with perceived turbine noise or attitude to wind turbines, as the authors imply. Furthermore, actual noise measurements were not made, and small urban wind turbines are nothing like the rural giants that give rise to most complaints considered to represent "wind turbine syndrome". The authors' bias is also evident in describing "wind turbine syndrome" as "non-specific symptoms"; in fact, Pierpont recognized a recurring set of symptoms that suggest inner ear disturbance. Others have attributed the complaints as compatible with sleep disturbance, a factor that Taylor/Lawrence do not seem to have considered. The concluding sentence of the abstract also reveals bias by insisting that NOP plays the key role (not just a contributing role) and that any noise or other disturbance is perceived but not "actual".

The link between health complaints and wind turbines: support for the nocebo expectations hypothesis
Fiona Crichton, Simon Chapman, Tim Cundy and Keith James Petrie
Frontiers in Public Health, 2:220 (2014). doi:10.3389/fpubh.2014.00220

Abstract:  The worldwide expansion of wind energy has met with opposition based on concerns that the infrasound generated by wind turbines causes health problems in nearby residents. In this paper we argue that health complaints are more likely to be explained by the nocebo response, whereby adverse effects are generated by negative expectations. When individuals expect a feature of their environment or medical treatment to produce illness or symptoms then this may start a process where the individual looks for symptoms or signs of illness to confirm these negative expectations. As physical symptoms are common in healthy people, there is considerable scope for people to match symptoms with their negative expectations. To support this hypothesis we draw on evidence from experimental studies that show that, during exposure to wind farm sound, expectations about infrasound can influence symptoms and mood in both positive and negative directions, depending on how expectations are framed. We also consider epidemiological work showing that health complaints have primarily been located in areas that have received the most negative publicity about the harmful effects of turbines. The social aspect of symptom complaints in a community is also discussed as an important process in increasing symptom reports. Media stories, publicity or social discourse about the reported health effects of wind turbines are likely to trigger reports of similar symptoms, regardless of exposure. Finally, we present evidence to show that the same pattern of health complaints following negative information about wind turbines has also been found in other types of environmental concerns and scares.

Update:  Chapman openly joins forces with the industry:

Fomenting sickness: nocebo priming of residents about expected wind turbine health harms
Simon Chapman, Ketan Joshi and Luke Fry
Frontiers in Public Health, 2:279 (2014). doi: 10.3389/fpubh.2014.00279

Abstract:  A nocebo effect hypothesis has been proposed to explain variations in where small minorities of exposed residents complain about noise and health effects said to be caused by wind farm turbines. The hypothesis requires that those complaining have been exposed to negative, potentially frightening information about the impact of proposed wind farms on nearby residents, and that this information conditions both expectations about future health impacts or the aetiology of current health problems where wind farms are already operational. This hypothesis has been demonstrated experimentally under laboratory conditions, but case studies of how this process can operate in local communities are lacking. In this paper we present a case study of the apparent impact of an anti wind farm public meeting on the generation of negative news media and the subsequent expression of concerns about anticipated health and noise impacts to a planning authority approval hearing in Victoria, Australia. We present a content analysis of the negative claims disseminated about health and noise in the news media and available on the internet prior to the hearing, and another content analysis of all submissions made to the planning authority by those opposing the development application.

Now they have lowered the bar from denial of actual health consequences of actual wind turbines to decrying the fact that raising concerns about adverse effects of wind turbines during a permitting process meant to raise concerns, raises concerns, even though the permitting agency ignored those concerns anyway.
