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.

Researchers at the Los Alamos National Laboratory and Sandia National Laboratories, conducted detailed studies that measured infrasound emitted from the 60-turbine Red Mesa Wind Farm situated in Laguna Pueblo, New Mexico, USA. The infrasound was found to travel out to 90 KM from the source. The abstract of the paper is provided below. The full paper can be downloaded from the links on this page.
These documents, secured under the Australian Right to Information (RTI) Act, reveal that warnings from the Queensland Government's own noise expert were not provided to the public or passed on to the Planning Department or the Minister for Planning to inform the wind turbine siting process. Dr Antoine David, the noise expert in the Department of Environment and Heritage Protection provided his superiors with a list of nine points of concern regarding the draft Wind Farm Code. The list of his concerns is provided below and can also be found on page 7 of the attached document. A RTI request revealed that, despite making his concerns known within his department, Dr. David's findings were not forwarded to the Department of Infrastructure, Local Government and Planning, the department responsible for developing the current draft (version 2) of the Wind Farm Code.
The Australian Senate Select Committee on Wind Turbines, which was established in December 2014, released this final report based on a considerable volume of evidence collected from testimonies around the country and beyond. The committee received written and verbal evidence from State Governments, local councils, various federal government agencies, wind farm operators and manufacturers, country fire authorities, acousticians, medical experts and representatives from various associations and institutes. In addition, many private citizens had the opportunity to voice their concerns with the planning, consultation, approval, development and operation of wind farms in Australia. The recommendations from both the interim and final reports are provided below. The full reports, both final and interim, can be accessed by clicking the links on this page. In addition, a minority, dissenting report is included.
Dr. McMurtry is Professor Emeritus of Western University in London, Ontario. He has researched and reviewed the health impacts of wind turbines for nearly a decade. He appeared before the Australian Senate Select Committee on Wind Turbines on June 29, 2015. The transcript of his appearance is provided below. A full transcript of the day can be found by clicking the link(s) on this page.
Clive and Petrina Gare presented their story before the Australian Senate Select Committee on Wind Turbines. The Gares leased their land to a wind developer for 19 turbines to be erected. The nearest turbine was sited about 800 metres away from their home with three towers within approximately one to 1.5 kilometres away. In total, they were paid $200,000 per year for hosting the machines. The construction phase was difficult but when the turbines were placed in service in October 2010, the situation became unbearable. The Gares, and others, gave testimony before the Australian Senate Select Committee on Wind Turbines. The full testimony is provided below can be accessed by clicking the links on the page.

Dr Christopher Hanning submitted this testimony to the Australian Senate Select Committee on Wind Turbines explaining the impact of turbine noise on sleep. The summary of his testimony is provided below. The full submission can be accessed at the links on this page.
The Acoustic Group’s Principal, Mr Steven Cooper, was commissioned by wind developer Pacific Hydro to undertake an investigation into “noise” emitted at the Cape Bridgewater wind energy facility. Symptoms reported by residents living near the turbines include severe nausea, headaches, ear pressure, inability to concentrate, and severe and debilitating sleep problems. The primary document explaining the study and the results can be downloaded from this page. The full study, including six appendices, can be accessed by clicking the links on this page.
This important study examines the noise emissions of an operating wind facility during periods when the turbines are generating electricity and when the turbines are shut off. The abstract of conclusion of the study are provided below. The full study can be accessed at the links on this page. The study found "consistent and significant differences in noise spectra ...for the shutdown and operational cases, particularly for frequencies below 100 Hz. These differences can be observed at distances up to 8.7 km from the wind farm.
Acoustician, Steven Cooper, has been asked to measure noise emissions at the Cape Bridgewater wind energy facility in Australia following years of noise complaints since the project was placed in service in 2008. Mr Cooper has tested inside three homes near the wind facility over eight weeks, including a two-week shutdown of the turbines. His preliminary report can be accessed by clicking the link(s) on this page. His initial findings are provided below.
This report describes the results of full spectrum acoustic monitoring conducted at a number of homes located between 2 km out to nearly 10km from the Waterloo Wind Energy facility. This monitoring was independent of the that conducted by the South Australian Environment Protection Authority (SA EPA) and was requested by Mrs Mary Morris and other concerned residents in the Waterloo district. The monitoring occurred during the period of the South Australian EPA Acoustic Survey, conducted in mid 2013. The conclusions of the monitoring are provided below. The full report can be accessed by clicking the link(s) on this page.
Dr. Bruce Rapley filed this response letter with the Australian Medical Association (AMA) objecting to the AMA's position on wind turbine noise that the "available Australian and international evidence does not support the view that the infrasound or low frequency sound generated by wind farms, as they are currently regulated in Australia, causes adverse health effects on populations residing in their vicinity." The concluding paragraphs of the letter are posted below. The full letter can be accessed by clicking the links on this page.
This important paper prepared by acoustics expert Les Huson examines the permitted noise limits imposed on the Flyers Creek wind energy facility in the context of actual infrasound noise emissions from other operating wind projects. Mr. Huson determines that the Flyers Creek project will not satisfy the noise conditions or the South Australian EPA Environmental Noise Guidelines for wind energy facilities. Excerpts of the paper are provided below. Readers are encouraged to download and read the full paper by clicking the link on this page.
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.
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.
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.
