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
‘Sensing but not Hearing’: Steven Cooper On Wind Turbine Nuisance-Part 2.
'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.
