Wind turbines more annoying than expected

The Windfarm perception project shows that the sound of wind turbines causes relatively much annoyance. The sound is perceived at relatively low levels and is thought to be more annoying than equally loud air or road traffic. This may be caused by the swishing character of the sound or because at night it does not decrease in strength -which is usually the case for traffic noise. Also in this study more disturbance of sleep occurs at the highest sound levels that occurred in this study. ...In the WINDFARM perception project, supervised by Frits van den Berg, the perception was investigated of modern, tall wind turbines by Dutch residents. The study shows that sound from wind farms is an important disadvantage of wind energy which in itself is positively appreciated by a majority of the participants.

Project WINDFARMperception: Visual and acoustic impact of wind turbine farms on residents

Wfp-final-1_thumb This report gives the results of the EU financed study WINDFARMpertception on how residents perceive a wind farm in their living environment as far as sound and sight are concerned. The study includes a postal survey among Dutch residents (n = 725, response rate: 37%) and an assessment of their aural and visual exposure due to wind farms in their vicinity.

Effects of the wind profile at night on wind turbine sound

Gpvandenberg_thumb This significant research by van den Berg explains why turbine noise as far away as 1900 meters (more than 6,000 feet) is resulting in complaints by residents particularly at night. The paper concludes that noise immission predictions are not accurate and result in the understating of turbine noise levels, particularly during nighttime conditions.
