This important report prepared by noise acoustician, Robert Thorne PhD of Noise Measurement Services in Australian, provides a comprehensive explanation of our "state of understanding" regarding wind turbine noise and the effects of the noise on communities. This report is updated from a previously released version of Dr. Thorne's study.
The Vermont Public Service Board held a prehearing conference on January 8, 2014 to discuss opening an investigation into the issue of appropriate sound standards applicable to facilities constructed pursuant to 30 V.S.A. §§ 248 and 219a. This inludes wind energy facilities. In this order the Board established a process for conducting the proceeding, as well as a proposed scope of issues to be examined through the investigation. A portion of the order is provided below. The full order can be accessed by clicking the link(s) on this page.
Ted Hartke, his wife Jessica and their two children, Phillip (age 9) and Sophia (age 6) have abandoned their home in Vermilion County, Illinois due to turbine noise. This testimony was delivered to the Boone County Illinois county commissioners on May 28, 2013 as the county considered a wind ordinance that would permit wind development. This testimony predates Mr. Hartke and his family leaving their home. A portion of his testimony is provided below. His full testimony can be accessed by clicking the link on this page.
This paper discusses Blade Passing Frequency (BPF) infrasound and its harmonics. Some results on Low Frequency Noise at discrete amplitude modulated frequencies of about 20 Hz plus harmonics, is briefly discussed as a side effect of the spinning mode generation mechanism. A portion of the paper is posted below. The entire paper can be accessed by clicking the links on this page.
Canadian health professionals Roy D. Jeffery, MD, Carmen M.E. Krogh, BScPharm, and Brett Horner, BA, published this peer reviewed paper which examines current literature on the impact of wind turbine noise emissions and the impact on residents nearby. The introduction and conclusions of the paper are provided below. The full paper can be accessed by clicking on the links on the page.
Nate Seltenrich, a science and the environment writer, explores wind turbine noise. In this report, he writes that "anecdotal evidence strongly suggests a connection between turbines and a constellation of symptoms including nausea, vertigo, blurred vision, unsteady movement, and difficulty reading, remembering, and thinking." An excerpt of his report is provided below. The full article can be accessed by clicking the links on this page.
Senator Madigan of Victoria in Australia delivered this speech on the floor of the Australian Senate wherein he announces findings from freedom of information requests that show the Waubra wind farm to be noncompliant, yet the agencies responsible for enforcement of the permit(s) say otherwise. In the speech, Senator Madigan explains that Waubra's breaching of its planning permit conditions is part of a broader culture of noncompliance arising from "systemic regulatory failure that impacts every wind farm in Victoria." The Senator's full speech is provided below and can be downloaded by selecting the link on this page.
Two weeks ago, in the injunction hearing in the Town of Falmouth vs. the Falmouth Zoning Board of Appeals case where the ZBA decided that the wind turbines were a nuisance to Neil Andersen, both parties presented a 7AM to 7PM agreement to the judge. Falmouth Selectmen subsequently disregarded that agreement and continued to run the wind turbines 5AM to 9PM. One selectboard member advocated running the turbines 24/7 in spite of the Court's request. Hearing this, Superior Court Justice Christopher Muse granted the injunction sought by nearby residents. The order is available by clicking the link on this page.
Dr. Michael Nissenbaum, who conducted extensive research into the effects of of audible wind turbine noise on sleep disturbance, has written a paper that explains his findings to other medical professionals who are unaware of the issue. The summary of his paper appears on this page. The complete document can be accessed by clicking on the link on this page.
This letter, which was read at the Vermilion county board meeting on Monday, October 8, 2013, was written by William C. Mulvaney, the Superintendent of Schools for Armstrong Township High School and Armstrong-Ellis CUD #61 in Illinois. The project is Invenergy's California Ridge with 134 turbines in Vermilion and Champaign counties. The setback at the time of construction was 1000 feet from the foundation of a family home. The setback was later changed to 1200 feet from the foundation. Mr. Mulvaney served on a wind ordinance panel. His message about students and families suffering the impacts of turbine noise and flicker is important.
This useful paper examines the response of study participants to wind turbine noise and associated amplitude modulation sound that is aerodynamically produced by the blades. The authors found that the maximum sound pressure level with fast time A-weighting (LAF max) best explained the annoyance characteristics as compared to the other descriptors considered. Excerpts of the report are provided below. The full study can be downloaded by clicking the links on this page.
In this letter to the Association of Australian Acoustical Consultants (AAAC), Dr. Alec Salt responds to the AAAC's position on wind turbine emissions and infrasound. In particular, Dr. Salt admonishes the AAAC for insisting that low-frequency sound emitted by turbines is no higher than infrasound levels measured at locations where other people live, work and sleep.
Tribunal de Grande in Montpellier in France found that the visual and audible impacts of an operating wind facility on the owners of the Eighteenth Century Château de Flers in the northern French province of Nord-Pas-de-Calais were unreasonable and ordered the ten turbines be removed. A summary of the Tribunal's ruling is provided below. The full order can be found by clicking the link(s) on this page.
This letter, written by William Hallstein, MD, a practicing psychiatrist with over 40 years of experience, was delivered to the Chairman of the Falmouth Board of Health. Dr. Hallstein is also a resident of Falmouth Massachusetts. In his letter he explains the very real impact of the Falmouth turbines on human health.
This important paper examines infrasound and its capacity to affect human health. The paper confirms that moderate strength correlations occur between the incidences of infrasound and reports of nausea, malaise, fatigue, aversion to the area, non-specific pain, and sleep disturbances when pressure levels exceed about 50 db for protracted periods. Because cells interact through the exchange of minute quanta of energy that corresponds with remarkably low levels of sound pressure produced by natural phenomena and wind turbines upon the body and its cavities, traditional standards for safety and quality of living might not be optimal. Included below is an excerpt of the paper pertaining to wind turbines. The full paper can be accessed by clicking the link(s) on this page.
This paper examines the connection between wind turbine noise and the factors that trigger motion sickness. The authors looked at the infrasoundic emissions at the Shirley wind facility in Wisconsin and assessed the frequency of motion sickmess and the possibility of the turbine noise being the cause. Excerpts of the paper are provided below. The full paper can be accessed from the links on this page.
This important published by acoustician, Paul Schomer and others provides an explanation for why some people are experiencing motion sickness and other ill-effects related to wind turbine acoustic emissions. This paper will be presented at the 5th International Conference on Wind Turbine Noise to be held in Denver, Colorado in August 2013. The summary and conclusions of the paper are provided below. The full paper can be accessed by clicking on the links at the bottom of this page.
In testimony provided before the Wisconsin Public Service Commission in reference to the Highland Wind Farm proposal (102.5 megawatts), acoustician Paul Schomer provides important perspective on why modern wind turbines installed today are creating a greater risk to nearby residents. Excerpts of his testimony are provided below. The full testimony can be accessed by clicking on the links at the bottom of this page.
This letter, submitted to the Massachusetts Department of Environmental Protection (MA DEP) details the appropriate methodology for surveying turbine noise post-construction. The procedure was developed under the guidance of acoustician, Richard James of E-coustics Solutions. The criteria for compliance is specific to the Massachusetts state law regarding noise and will differ from other jurisdictions. However, the procedure should be consistent for all noise surveys.
