17th February, 2015 By Peter Collins, The Standard Source; https://www.standard.net.au/story/2887288/acoustic-study-links-cape-bridgewater-wind-farm-noise/ Pacific Hydro has agreed further study is required to obtain a rigour to withstand scientific scrutiny. PACIFIC Hydro has declared it won’t be paying compensation or modifying operation of its Cape Bridgewater wind farm following an acoustic study which found a link between infrasound and … Continue reading Acoustic Study Links Cape Bridgewater Wind Farm, Noise-2015
http://www.windaction.org/posts/38138-a-proposed-metric-for-assessing-the-potential-of-community-annoyance-from-wind-turbine-low-frequency-noise-emissions#.Xy5gGChKjIU This paper, presented at the Windpower ’87 Conference & Exposition in San Francisco by N.D. Kelley, a physicist at the Solar Energy Research Institute in Golden, Colorado validates the fact that turbines (both upwind and downwind) produce low-frequency sound emissions that can negatively impact humans within their homes. Although modern wind turbines are different … Continue reading A Proposed Metric For Assessing The Potential Of Community Annoyance From Wind Turbine Low-Frequency Noise Emissions- 1987

WIND TURBINE NOISE A Simple Statement of Facts – The Australian Experience Waubra Foundation-March 2016 Source: https://waubrafoundation.org.au/resources/wind-turbine-noise-simple-statement-facts-australian-experience/ Emission of Sound and Vibration Wind turbine blades produce airborne pressure waves (correctly labelled sound pressure waves but often called noise). Noise is that portion of the sound which is audible. The loudness, or power, of the sound … Continue reading Wind Turbine Noise – A Simple Statement of Facts – The Australian Experience
'I suggest that with respect to the description of wind turbine noise it is a matter of terminology that needs a shift as follows:
The language should be pulsations at an infrasound rate.
Modulation of the entire signal at an infrasound rate. (Zwicker and Fastl call this fluctuation as a sensation detected by the ear).
AM is present as some discrete low frequencies modulated at the bpf.
UK method of AM is determining the modulation index of the fluctuating signal (not technically AM).
You can determine the Modulation Index of the low frequency noise that is AM.' -Steven Cooper.
November 6, 2019 By Sherri Lange-Master Resource Source: https://www.masterresource.org/wind-turbine-noise-issues/sensing-not-hearing-cooper-qa-1/ Congratulations to Steven Cooper on his appointment to the European Acoustics Association Technical Committee on Noise, as the group leader on wind turbine noise, and on presenting three papers at the International Congress on Acoustics in Germany. ~DeFrock. “But wind turbine noise issues are not just … Continue reading ‘Sensing but not Hearing’: Steven Cooper On Wind Turbine Nuisance-Part 1.
'The plaintiffs claim that developers built the project too close to their homes and as a result, have created a number of hazards and adverse health effects, including sleep disturbance, annoyance, headaches, dizziness, vertigo, nausea, motion sickness, bodily sensations, fatigue, stress, depression, memory deficits, inability to concentrate, anxiety and an overall reduced quality of life. The complaint says that these effects are largely due to the shadow flicker and loud noise that comes from the turbines when they are in motion.'
