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 →
