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 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. The abstract and conclusion of the paper are provided below. The full report can be accessed by clicking the links on this page.
FINLAND. Aunio Group Oy from Oulu has developed a device for measuring and recording infrasound produced by wind turbines. The measurement equipment can be used to produce research data for investigating the characteristics of infrasound and where it spreads, and to analyze any health problems it may cause. The infrasound produced by wind turbines differs from infra-sounds occurring in nature; according to measurements the infrasound produced by wind turbines is a clear signal - distinguishable from ambient noise in the environment. This paper describes the method of evaluating the Anuio Group's device and the results. The full paper can be accessed by clicking the links on this page.
At the September 6, 2017 meeting of the Somerset County Maine Commissioners, the Board adopted Resolution 17 – 164 that publicly opposes any additional industrial Wind Development in Somerset County. The agenda for the meeting can be found here. The full resolution, as adopted, is provided below and can be accessed at the links on this page.
In November 2014, Health Canada released the results of its $2.1 million “Wind Turbine Noise and Health Study.” Despite public anouncements from Health Canada that the raw data originating from the Study would be made available, the data continues to be inaccessible making it impossible to validate the conclusions drawn by Health Canada researchers. For example, HC found high levels of annoyance but concluded no association to turbine noise.
In this important ruling issued by Massachusetts Superior Court Judge Cornelius J. Moriarty II, the court ordered that the decision of the Falmouth MA Zoning Board of Appeals be affirmed to the extent that the operation of Wind 1 and Wind 2 constitute a nuisance and that the Town of Falmouth cease and desist operation of the wind turbines immediately.

This important study has identified flaws in the current compliance testing for wind turbine noise and further outlined the methods necessary for identifying and measuring the low-frequency, pulsation that isoften times reported by those impacted by the turbines. Specifically, the "presence of amplitude modulation in the low frequency region, that modulates at an infrasound rate, at or near the threshold of hearing" has been identified and may support the symptoms reported by Dr. Nina Pierpont in her work, Wind Turbine Syndrome. The introduction and conclusion of the paper is provided below. The full paper can be accessed by clicking the links on this page.
ABK Energy secured a contract to purchase and install six German-made Nordex turbines (18 MW) on private and public land located in Cesme Turkey. The Cesme wind energy facility was opposed by residents who took their objections to the court. In January 2014, the same time when construction was started, the court issued a stop order. Permission to proceed with building the project was ultimately withdrawn after the court ruled the project was not in the “public good and interest.” The below statement was issued by environmental lawyer, Mehmet Horuş following the court's decision.
The authors provide a compelling argument that shows how Canadian residents have been exposed to harmful emissions from wind turbines without their consent. The abstract of the paper and summary comments are provided below. The full paper can be accessed at the document links on this page.
This important paper examines the issues surrounding wind turbine noise emissions, the impact of the noise on residences nearby, and how public health professionals have failed to closely examine legitimate complaints.

The findings of this study demonstrate that infrasound near the hearing threshold may induce changes of neural activity across several brain regions, some of which are known to be involved in auditory processing, while others are regarded as keyplayers in emotional and autonomic control. In other words, sound that is not audible can still trigger a response in the human brain.
NextEra's Golden West Wind Energy Center sited in El Paso County, Colorado was required under the County permit to conduct a noise impact study after the project was placed in service in October 2015. Acoustician Robert Rand was asked by residents living near the turbines to review the noise impact study as prepared by NextEra consultant, Epsilon Associates. Mr. Rand's report, included here, identified several material errors with Epsilon's report and also found that the project appears to be operating outside the noise limits permitted by the County and the State. The Golden West Wind Energy Center consists 145 1.72-megawatt GE turbines for a total installed capacity of 249.4-megawatts Mr. Rand's executive summary is provided below.

These papers document an important debate between wind-friendly academics who argue that those living near wind turbines benefit from the experience and those who insist such conclusions are backed by inappropriate study methodologies and broad assertions that cloud actual findings. In this circumstance, Dr Daniel Shepherd a PhD in psychoacoustics and head of research at AUT University in Auckland, New Zealand, challenges the methods and conclusions of Mroczek et al.’s “Evaluation of Quality of Life of Those Living near a Wind Farm“ published in the International Journal of Environmental Research and Public Health, 2015, 12, 6066–6083. The academic editors of the Journal, after granting Mroczek the opportunity to respond, agree with Shepherd's main criticisms. In total, there are four papers documenting this debate; three are attached to this page. These include Shepherd's critique, Mroczek's response and the position of the Journal's academic editors. Portions of the response by the Journal's editors are also provided below.

As part of the New York State Article 10 process for reviewing wind energy proposals, the Department of Health has submitted these scoping comments to the developer of the proposed Eight Point wind energy facility. Project developer NextEra plans to erect 32 wind turbines totaling 103.4 megawatts on land leased in the towns of Greenwood, West Union and Troupsburg and West Union in Steuben County, New York. The Department of Health has raised important questions regarding the cumulative impact of the project on health and safety given there are existing wind projects in the same general area. The cover letter addressed to NextEra is provided below. The full letter with comments can be accessed by clicking the document icon on this page.
This important peer-reviewed paper examines 15 years of the authors' combined experience with wind turbine noise issues. The authors respond to the various responses by the wind industry regarding turbine noise and explain why audiologists, particularly those interested in community noise, should embrace the notion that all forms of noise, if sufficiently intense and prolonged, can be detrimental to public health. They also encourage audiologists to be sensitive to the non-auditory aspects of acoustic energy, including the dynamically modulated infrasound and low-frequency sound emitted by modern wind turbines. The background information about the paper is provided below. The link(s) to download the paper are included on this page.
This important paper examines how wind turbine noise, particularly noise from larger turbines, falls in the lower frequency range, below 1000 and 500 Hz. This type of noise penetrates homes and creates sleep disturbance. The researchers found that, in general, the indoor noise levels of homes near turbines are higher which helps explains noise annoyance complaints. The abstract of the paper is provided below.

In this open letter, Barbara Ashbee of Mulmur, Ontario, together with hundreds of other Ontarians, sent an open letter to Health Minister Jane Philpott, asking why Health Canada has not insisted wind energy corporations report citizen complaints about noise radiation.The letter, attached here, asks the minister to meet with Ms. Ashbee and representatives of citizens suffering from turbine noise radiations. An excerpt of the letter is provided below. The full letter can be accessed by clicking the links on this page.
Phase I of the Bent Tree Wind Project began operation in January 2012. The project consists of 122 Vestas V82/1650 (1.65 MW, diameter 82 m) turbines for a total installed capacity of 201.3 megawatts. Noise complaints were filed by at least two landowners since September 2015. Staff for the Energy Environmental Review and Analysis (EERA) unit of the MN Department of Commerce examined the complaints and believe the complaints are both Unresolved and Substantial. In this letter with supporting documentation, EERA staff recommended the MN Public Utilities Commission initiate the process for addressing the complaint. The letter to the PUC is provided below.
