Wind Turbine Noise: Real Impacts on NeighborsBy Lisa Linowes -- March 1, 2019 4 Comments
“ When neighbors complain of disturbed sleep, [wind noise models] might cite a predicted level of 40 dBA, when the actual noise that triggered awakening was a 50+ dBA spike, making turbine noise the problem.”
“Hessler & Associates agreed ‘that a wind turbine is indeed a unique source with ultra low frequency energy’ and that a ‘new Threshold of Perception’ was needed to assess turbine noise impacts.”
“Former Vestas’ CEO, Ditlev Engel has admitted that larger setback distances are the only way to address low frequency and infrasonic impacts, particularly on larger (3MW) turbines. Bigger setbacks means fewer locations for siting turbines near where people live.”
In late January, the Iowa Policy Project, Iowa Environmental Council, and the University of Iowa’s Environmental Health Sciences Research Center (IPP et al.) jumped on the ‘wind energy is safe’ bandwagon with a joint release claiming wind turbine noise does not pose a risk to human health.…
World Health Organization: Wind Turbine Noise as a Health Hazard (opening recognition likely to lead to more acknowledgement)By Sherri Lange -- October 17, 2018 20 Comments
“The wind industry has denied and ignored evidence directly linking wind turbines and sleep disruption leading to negative human and animal impacts worldwide. Expect WHO’s new Guidelines to give rise to new standards to mitigate if not eliminate this ongoing suffering.”
“The burden of environmental noise with wind turbines is not episodic or random: for the most part its effects are constant and unrelenting…. This is an undeniable health pressure of enormous magnitude.”
Abstract: While only “conditional,” acknowledgement is given to pulsation (impulsive amplitude modification, as Steven Cooper calls it) and ILFN (Infra and Low Frequency Noise), the new World Health Organization report underscores the failure of current regulations of dB to manage health impacts from industrial wind installations worldwide.
The other irrefutable conclusion is that the wind industry has been given a regulatory path to profits with an unfathomable license to hurt in the form of sleep deprivation (and associated disease) for a very long time.…
Sensing but Not Hearing: The Problem of Wind Turbine Noise (Interview with acoustician Steven Cooper, AU)By Sherri Lange -- February 2, 2018 13 Comments
Editor Note: Steven Cooper has advanced our understanding of how people react to real recorded pressure pulsations from industrial wind turbines. In the last six months he has presented eight papers at Acoustic Meetings in Zurich, Boston and New Orleans. With this interview, he breaks down some of the salient points of his research discoveries. Cooper’s work is expanding our knowledge about “soundscapes” near projects, which could result in new legal requirements for manufacturers and developers.
“In general, wind farm applications claim that turbines do not generate any low-frequency, tonal, or impulsive characteristics, which is a matter disputed by residential receivers. The consequence of the pulsating signal generated by turbines (whether audible or inaudible) could potentially require a further adjustment to any perception or impact generated by wind turbines.”
“On discussing the resident’s observations (with the residents) for the first two weeks I found the use of describing the impacts in terms of Noise, Vibration, and Sensation was accepted by the residents as a better concept.”

Wind Turbine Noise: What Isn’t Heard Can Harm YouBy Brian Dubie -- October 15, 2015 1 Comment
“So, when you think of industrial wind turbines on a ridge line, envision an airport with a line of airplanes that are holding for take-off. The airplanes are powered by chainsaw engines that have run up their engines to full power. But, unlike planes at an airport, the turbines never take off. Now, imagine this at two o’clock in the morning.”
What do you think of when you think of an industrial wind project? Wind developers want you to think of free, green electricity. People who live near industrial wind turbines think of noise. Let’s see why.
An industrial wind project in Swanton, Vermont proposes to install seven 499-foot tall wind turbines along 6,000 feet of Rocky Ridge (elevation 323 feet). We don’t know what turbine model the developer is considering, so let’s look at the GE 2.75-120 Wind Turbine.…
