Low Frequency Sound and Infrasound from Wind Turbines
Presenters Robert O'Neal, Epsilon Associates Robert Hellweg, Epsilon Associates Richard Lampeter, Epsilon Associates
Description A common issue raised with wind energy developers and operators of utility-scale wind turbines is whether the operation of their wind turbines may create unacceptable levels of low frequency noise and infrasound. In order to answer this question, one of the major wind energy developers commissioned a scientific study of their wind turbine fleet.
The study consisted of three parts:
a world-wide literature search to determine unbiased guidelines and standards used to evaluate low frequency sound and infrasound,
a field study to measure wind turbine noise outside and within nearby residences, and
a comparison of the field results to the guidelines and standards.
The study concludes that there should be no adverse effects from infrasound or low frequency noise at distances greater than 305 meters from wind farms with the wind turbine types measured.
Details of the study will be presented at the GBC/ASA meeting.
