From the conclusion of this study: The purpose of this article is to compare the qualitative and quantitative methodologies and to describe the benefits of having used a qualitative methodology, specifically Grounded Theory in order to study why some people contemplate vacating/abandoning their homes when living within 10 km of industrial wind turbines. ...As described in this article, the siting of industrial wind energy facilities in rurally populated areas can challenge a quantitative methodology due to such factors as low population density, obtaining a sufficient sample, and challenges to achieving statistical power and statistical significance. Grounded Theory methodology served as a practical toolThis important analysis validates the claim that people living in proximity to industrial scale wind turbines who have made house decisions to leave their homes did so based on the impacts of the turbines.

BACKGROUND: Over the past two decades, the increasing and unregulated production of infrasound and low frequency noise (ILFN, ≤200 Hz) has led to a considerable rise in associated noise complaints and health-related issues. The most recent of such ILFN sources are industrial wind turbines (IWT). Acoustical field-data was collected within a home located in the vicinity of IWT, to which the AUC Rule 012 and its requirements were applied. In Ontario, IWT noise complaints were gathered under the Freedom of Information legislation. Goal: To explore the usefulness of current noise control rules when protecting human populations against ILFN generated by IWT.
BACKGROUND: Noise from wind turbines (WTs) is associated with annoyance and, potentially, sleep disturbances.
The pilot study carried out in Satakunta and Northern Ostrobothnia in Finland shows that the damage caused by infrasound from wind power plants will only decrease significantly more than 15 kilometers away from wind turbines. The study was carried out by the Finnish Association for Environmental Health (SYTe) in the spring 2016. A portion of the study's results is provided below. The full report (in English) can be found at the document links on this page.
There were 4574 Incident Reports/Complaints regarding wind turbine operation received by Ontario’s hotline in the period from 2006-2016. More than 50% of the 3000 complaints received from 2006 to 2014 had no response from the government. Another 30% were noted as “deferred” response while only 1% of the reports received a priority response. This important report examines the incident reports and highlights the role of the reports in assessing public health concerns.
Audiologist Dr. Jerry Punch, a professor emeritus in the Department of Communicative Sciences and Disorders, submitted comments in regard to a wind energy facility before the Ohio Power Siting Board. Dr. Punch's comments focus on the impacts of wind turbines noise on human health. A portion of his comments are provided below. His complete letter can be downloaded at the links on this page.
This important paper examines the highly touted Health Canada study that looked at wind turbine noise and its impact on human health. The authors cite serious limitations of the Health Canada methodology and the failure of Health Canada to honor its original intention of releasing the raw data for other researchers to confirm and test Health Canada's findings. Readers are encouraged to read this paper closely before accepting the reported findings of the Health Canada study.
Dr. Riina Bray, the Medical Director of the Environmental Health Clinic at Women’s College Hospital, Associate Professor in the Department of Family and Community Medicine and former Chair of the Environmental Health Committee of the Ontario College of Family Physicians submitted this letter to the Premier of Ontario, The Honorable Doug Ford, addressing the health concerns related to wind turbines. The letter is provided below. The full letter including all references can be accessed at the links on this page.
This important letter to the Town of Falmouth (Massachusetts) explains how the relocation of the Wind 2 turbine would result in continued noise violations. The author, Robert Rand, an acoustician experienced in turbine noise, warned that the turbine would need to be situated at least 2923 feet from the nearest neighbor in order to remain in compliance with governing noise regulations. The letter is posted below and accessible by clicking the document icon on this page. The supporting evidence is included with the document.
ABSTRACT: This review considers the nature of the sound generated by wind turbines focusing on the low-frequency sound (LF) and infrasound (IS) to understand the usefulness of the sound measures where people work and sleep. A second focus concerns the evidence for mechanisms of physiological transduction of LF/IS or the evidence for somatic effects of LF/IS. While the current evidence does not conclusively demonstrate transduction, it does present a strong prima facia case. There are substantial outstanding questions relating to the measurement and propagation of LF and IS and its encoding by the central nervous system relevant to possible perceptual and physiological effects. A range of possible research areas are identified.
This important paper has found living close to wind turbines "is negatively correlated with self-rated environmental quality of life and physical health quality of life." The finding is consistent with other studies cited in the paper. The authors also found that turbine noise alone is not the only factor. Other factors may include "visual sight, vibrations, shadow flicker, sub-audible low frequency sound, or mechanisms that include individual subjective experiences and attitudes towards wind turbines." The results of the paper are posted below. The full report can be downloaded by clicking the links on this page.
This important letter by acoustician Stephen Ambrose explains how two separate court decisions, one in Massachusetts and the other in Michigan, together provide clarity on what the minimum protective noise limits should be when siting industrial wind energy facilities. Mr. Ambrose's letter includes links to the two decisions as well as supporting background information. The content of the letter is shown below. The original can be downloaded from this page.
This important decision by US District Court Judge Thomas L. Ludington addresses two arguments proffered by the wind industry. The first relates to the industry's argument that noise standards for limiting turbine noise emissions that are based on Lmax are not reasonable. The second discusses the argument that restricitve ordinances, in this case an Lmax noise limit, are de facto exclusionay zoning. Judge Ludington takes both claims on and finds the wind company's arguments are without merit. A portion of the decision is provided below. The full decision can be downloaded from this page.
This new report examines how locations where industrial wind turbines were erected near residences experienced measurable upticks in suicide. The researcher identifies three indirect tests of the role of low-frequency noise exposure including those most vulnerable to the noise, prevailing wind direction and potental of greater noise impacts, and turbine noise resulting in sleep deficiency.
