Low-frequency sound affects active micromechanics in the human inner ear

Low-frequencysound-drexl_thumb In this study, neurobiologist Markus Drexl and others at the Ludwig Maximilian University in Munich, Germany, examined the effects of low frequency noise on human hearing. The found that after short bursts of LF sound the ear showed signs that, over time could damage hearing. The introduction and conclusion of the study's report are provided below.

Noise impacts due to wind energy facilities on the acoustic ecology of a desert ecosystem

This study examines the impact of wind turbine sound emissions and the potential of masking of biological signals between species present in desert habitats. Turbine noise appear to increase the ambient noise level to the point where bioacoustic activity could not be detected. An abstract and summary of the report is provided below. The authors have not yet released the full report.

Cooper findings

Cooper-preliminary-findings-cape-bridgewater_thumb 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.

Noise monitoring in the vicinity of the Waterloo Wind Farm

Hansen-zajamsek-hansen-noise-monitoring-at-waterloo_thumb 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.

Letter to the Editor re: 'How the factoid of wind turbines causing ‘vibroacoustic disease’ came to be ‘irrefutably demonstrated’'

Alves-pereira_et_al-2014-australian_and_new_zealand_journal_of_public_health_thumb This informative response letter provides useful detail on the work of Mariana Alves-Pereira and her study of how wind turbine infrasound impacted the health of family members living near a wind project. Due to health concerns, the Supreme Court of Justice in Portugal ordered in 2013 that four of the wind turbines, initially erected in 2006, be removed. A portion of the document is provided below.

Dr. Bruce Rapley response to Australian Medical Association

Rapley-ltr_thumb 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.

Huson Review: Flyers Creek Wind Farm Approval

Huson-report-for-pac-14th-february-2014_thumb 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.

Ted Hartke Testimony: We abandoned our home

Hartke_submittal-wind_farm_experience_5-28-13_thumb 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.

Noncompliant wind farms: A Betrayal of the public's trust

Madiganspeech-2013-12-10_thumb 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.

Court order granting injunction; Falmouth turbine operations limited due to noise

Falmouthzbapreliminaryinjunctiondecisionandorder_thumb 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.
