Hearing Health & Technology Matters

October 5, 2016 — A new paper from acoustician Richard James and audiologist and professor emeritus Jerry Punch, just published in the journal Hearing Health Matters, confirms support for the idea that “acoustic emissions from IWTs [industrial wind turbines] is a leading cause of AHEs [adverse health effects] in a substantial segment of the population.”

The authors deal with 12 commonly held beliefs about wind power and health effects, promoted by the global wind power development industry, that do not support a connection between wind turbine noise and health problems. They conducted a comprehensive literature review, and review the findings of the most up-to-date studies, including the Cape Bridgewater study by acoustician Steven Cooper, which changed the language of wind turbine noise research.

A paper by Paul Schomer of the U.S. is quoted for example, and the authors conclude “some people affected by WTN [wind turbine noise] may be responding directly to acoustic factors, rather than to non-acoustic factors, as argued by Leventhall.” (page 21)

Canada figures in the paper with references to work done by Dr Roy Jeffery, Dr Robert McMurtry, and researcher Carmen Krogh, among others.

The authors wrote a ccovering letter for windaction.org in which they said,

Finally, let it not be said that either of us believes in making any less than the best possible effort to develop clean and efficient sources of energy. Rather, we hope that our article will be instrumental in promoting public health through a better understanding of the issues underlying the potentially harmful effects of audible and inaudible noise from industrial wind turbines when the turbines are sited too close to where people live and work.

Australian Senate report: dismayed by wind industry behaviour

As you may know, the Senate in Australia (which is an elected body) has been conducting a review of wind turbines and problems associated with wind power generation in that country for several months.

Although the final report is not due out until August, the Committee felt it necessary to release an interim report and the “headline recommendations.”

They are very interesting…and refreshing in that here is a body that has listened to both sides, and has concluded there is cause for concern.

Of particular interest are these three paragraphs from the report.

Why are there so many people who live in close proximity to wind turbines complaining of similar physiological and psychological symptoms? As with previous Senate inquiries, this committee has gathered evidence from many submitters attributing symptoms of dizziness, nausea, migraines, high blood pressure, tinnitus, chronic sleep deprivation and depression to the operation of nearby wind turbines. The committee invites the public to read and consider the evidence of people who have experienced these symptoms and who attribute their anxiety and ill health to the operation of turbines.2

1.13 These health affects should not be trivialised or ignored. The committee was particularly distressed by renewable energy advocates, wind farm developers and operators, public officials and academics who publicly derided and sometimes lampooned local residents who were genuinely attempting to make known the adverse health effects they were suffering.

1.14 The committee is aware of people complaining of these impacts who have since left their family home. Some now live a nomadic and uncertain existence. In one case, the now deserted home had been in the family for five generations—since the 1840s. These are not decisions taken lightly. Having left the turbine vicinity, several witnesses noted that the symptoms had faded if not disappeared.3

The Committee quite rightly observed that the decision to leave the family home, and often hundreds of thousands of dollars of investment, to say nothing of farm operations and property, because they HAD TO.

The recommendations listed by the Senate Committee include the need for independent clinical research, and continuous independent monitoring of wind power project noise and infrasound (oh, and we need standards and regulations for infrasound–Ontario doesn’t have these and is dragging its feet on this issue)—the Committee also vindicated the effort and methodology of acoustician Stephen Cooper whose Cape Bridgeport study and finding of unique “sensation” resulting from the turbine emissions.

Several months ago, Ottawa Wind Concerns was subjected to a barrage of insulting Tweets one evening from Australia from a pro-wind power physician, and acolytes of sociologist Simon Chapman. Mr Chapman is mentioned specifically in the Senate Committee report, presumably as one of the disappointing “academics.” (Mr Chapman also functions as a paid consultant for the wind power industry.)

The commentators that evening included one Chris Young of Ottawa who works in the renewable energy field (former Board member of the Ontario Sustainable Energy Association, and former employee of NorSun Energy). Mr Young, at the end of a trail of increasingly insulting posts claiming that people who reported health effects from turbine audible noise and infrasound were essentially nuts, said that Ottawa Wind Concerns, people like us, and specifically me, were “irrelevant.”

Now that we have a government body stating that there is cause for concern, that the wind power industry’s behaviour has been lamentable, and that the way forward is research that is actually intended to find out what’s going on, we ask, who is “irrelevant” now?

Health Canada brochure “misleading” Wind Concerns Ontario tells Minister of Health

A letter is heading for the Brooke Claxton Building at Tunney's Pasture

Health Canada headquarters at Tunney’s Pasture–not in touch with the reality in Ontario, says Wind Concerns Ontario

Wind Concerns Ontario has sent a letter to the federal Minister of Health, Rona Ambrose, expressing concern about the mailing of a promotional brochure connected to the Health Canada Wind Turbine Noise and Health study. The study results were released in a summary (no peer review, no actual report or paper) last November, but the brochure was not sent out until February 2015, by Canada Post Unaddressed Admail. The timing is unusual, coming so long after the study results release, and coinciding with Ontario’s new procurement process for large renewable power projects. It is also very unusual for a research team to create and release a brochure. That brochure is misleading, Wind Concerns Ontario president Jane Wilson said in the letter to the Minister. “It’s not true, as the brochure says, that there are no health effects from the wind turbine noise and infrasound–there are, and the study summary says that.  It says 16.5 percent of people studied who live within 1 km of a turbine were experiencing distress,” Wilson said. Wind Concerns Ontario met with Health Canada/Healthy Environments and Consumer Safety staff the day after the study results were released, and advised that the draft brochure not be released. “We told them that the disclaimer on the brochure, which explained that the study results were ‘preliminary’ and unreviewed, was not prominent enough,” Wilson said. “We also asked why they weren’t going back into the study communities in person, as is normal practice for scientific research teams, rather than sending a brochure.” Wind Concerns said that the study summary, and now the brochure, strain the credibility of Health Canada and the federal government in Ontario. “The fact is, the conclusion being promoted in the brochure from this study–that there are no health effects–does not coalesce with the real-life experience in Ontario communities,” Wilson said. “The people of Ontario were hoping that their federal health department would pull out all the stops to find a reason for the many, many reported health problems related to wind turbine noise—instead, they got short shrift in this study, and now an unnecessary and misleading, taxpayer-funded promotional brochure that functionally supports the wind power development industry.”

Health Canada needs to take action on wind farms: noise study “too little, too late”

November 28, 2014 Canadian Medical Association Journal blog

Carmen Krogh, BScPharm (retired), is a peer reviewed IWT health researcher and formerDirector of Publications and Editor-in-Chief of the CPS.

R Y McMurtry is Professor Emeritus (Surgery) of Western University (formerly University of Western Ontario). Dr. McMurtry was also anADM at Health Canada 2000-02

Industrial wind turbines (IWTs) are being erected at rapid pace around the world. Coinciding with the introduction of IWTs, some individuals living in proximity to IWTs report adverse health effects including annoyance, sleep disturbance, stress-related health impacts and reduced quality of life. [i],[ii],[iii],[iv],[v],[vi],[vii],[viii],[ix],[x],[xi],[xii] In some cases Canadian families reporting adverse health effects have abandoned their homes, been billeted away from their homes or hired legal counsel to successfully reach a financial agreement with the wind energy developer.[xiii]

To help address public concern over these health effects Health Canada (HC) announced the Health Canada Wind Turbine Noise and Health Study (HC Study) 2 years ago and brought forth preliminary results November 6, 2014.

Here we briefly comment on the HC Study results and provide some historical context.

Acknowledgement of IWT adverse health effects is not new. The term “annoyance” frequently appears when discussing IWT health effects.

In a 2009 letter the Honourable Rona Ambrose, disclosed:

“Health Canada provides advice on the health effect of noise and low-frequency electric and magnetic fields from proposed wind turbine projects…To date, their examination of the scientific literature on wind turbine noise is that the only health effect conclusively demonstrated from exposure to wind turbine noise is an increase of self-reported general annoyance and complaints (i.e., headaches, nausea, tinnitus, vertigo).” [xiv]

In 2009, the Canadian Wind Energy Association (CanWEA) sponsored a literature review which acknowledges the reported symptoms such as headaches, nausea, tinnitus, vertigo and state they “… are not new and have been published previously in the context of “annoyance”…” and are the “… well-known stress effects of exposure to noise …”[xv]

In 2011, a health survey of people exposed to IWTs in Ontario reported altered quality of life, sleep disturbance, excessive tiredness, headaches, stress and distress. [xvi]

In the same year, CanWEA posted a media release which advised those impacted by wind turbine annoyance stating “The association has always acknowledged that a small percentage of people can be annoyed by wind turbines in their vicinity. … When annoyance has a significant impact on an individual’s quality of life, it is important that they consult their doctor.”[xvii]

It turns out it’s not a small percentage of people annoyed by wind turbines. An Ontario Government report concluded a non-trivial percentage of persons are expected to be highly annoyed.

The December 2011 report prepared by a member of CanWEA for the Ontario Ministry of Environment states in the conclusions:

“The audible sound from wind turbines, at the levels experienced at typical receptor distances in Ontario, is nonetheless expected to result in a non-trivial percentage of persons being highly annoyed. As with sounds from many sources, research has shown that annoyance associated with sound from wind turbines can be expected to contribute to stress related health impacts in some persons.”[xviii]

The World Health Organization (WHO) acknowledges noise induced annoyance to be a health effect [xix] and the results of WHO research “…confirmed, on an epidemiological level, an increased health risk from chronic noise annoyance…”[xx]

HC also acknowledges noise induced annoyance to be an adverse health effect. [xxi],[xxii] The Principal Investigator of the recent HC Study also states “noise-induced annoyance is an adverse health effect”. [xxiii]

Canadian Government sponsored research has found statistically significant relationships from IWT noise exposure.

A 2014 review article in the Canadian Journal of Rural Medicine reports:

“In 2013, research funded by the Ontario Ministry of the Environment indicated a statistically significant relation between residents’ distance from the turbine and the symptoms of disturbed sleep, vertigo and tinnitus, and recommended that future research focus on the effects of wind turbine noise on sleep disturbance and symptoms of inner ear problems.” [xxiv]

Recently on November 6, 2014, HC posted on its website preliminary results of its HC Study[xxv]. Wind turbine noise “…. annoyance was found to be statistically related to several self-reporting health effects including, but not limited to, blood pressure, migraines, tinnitus, dizziness, scores on the PSQI, and perceived stress” as well as related to “measured hair cortisol, systolic and diastolic blood pressure.”

These troubling results come as no surprise. Since at least 2007 HC employees including the Principal Investigator of the HC Study recommended wind turbine noise criteria which they predict will result in adverse health effects. (i.e. result in an increase percentage highly annoyed).[xxvi],[xxvii],[xxviii]

Then turbines were built and HC spent 2.1 million dollars to find out it appears to have under predicted the impact of IWT noise. HC’s IWT noise criteria does not use a dose response based on IWT noise but rather road noise. But of course IWTs are not cars and peer-reviewed studies consistently document that IWTs produce sound that is perceived to be more annoying than transportation or industrial noise at comparable sound pressure levels. [xxix],[xxx]

IWT noise annoyance starts at dBA sound pressure levels in the low 30s and rises sharply at 35 dBA as compared to road noise which starts at 55 dBA. These findings are further supported by the HC Study’s preliminary results.[xxxi]

IWT noise characteristics that are identified as plausible causes for reported health effects include amplitude modulation, audible low- frequency noise (LFN), infrasound, tonal noise, impulse noise and night-time noise. [xxxii]

The logical solution would be to develop IWT noise criteria which will protect human health but that would present a barrier to wind energy development. Noise limits impacts IWT siting, cost of energy produced [xxxiii] and by extension corporate profits. The wind energy industry has actively lobbied governments to be granted IWT noise exposure limits which benefit their industry.

Canadians trying to understand this should be mindful the Government of Canada has invested and distributed significant amounts of public money to attract and support the wind energy industry. [xxxiv],[xxxv],[xxxvi],[xxxvii],[xxxviii],[xxxix],[xl],[xli] In addition to providing funding, the Government of Canada in collaboration with wind industry stakeholders has developed the Wind Technology Road Map (Wind TRM) [xlii] which Natural Resources Canada defined to be an “…industry-led, government supported initiative that has developed a long-term vision for the Canadian wind energy industry …”.[xliii]

Canada’s Wind TRM states “Members of the Steering Committee, government and our industry will be using this roadmap to direct the actions that are necessary for Canada to develop its vast wind resources.”[xliv] HC is a member of the Interdepartmental Wind Technology Road Map Committee [xlv] which was created to assist in the implementation of Canada’s Wind TRM. [xlvi] One of the “key action items” detailed in the Wind TRM calls for Government and Industry collaboration to develop and maintain government documents that address concerns raised about wind energy projects including that of noise, infrasound and other. [xlvii]

Some jurisdictions are trying to take action to protect their residents. For example, several municipalities in Ontario are trying to establish bylaws that protect from IWT noise. In Wisconsin, on October 14, 2014 the Brown County Board of Health unanimously approved a motion to declare the IWTs at a local project a Human Health Hazard. [xlviii]

It would appear HC’s research effort is too little too late. A non-trivial percentage of Canadians continue to experience adverse health effects. HC now has additional scientific evidence of the “conclusively demonstrated” effects from exposure to IWT noise. It is time for HC to take action to help Canadians maintain and improve their health.
