Wind turbine sounds no threat to humans

Apparently the “swish swish” (or is it “whup whup”?) of wind turbine blades has irked some folks living near them, leading to claims the sound is harmful to people. The American Wind Energy Association says today a study has found no threats created by the sounds.

Comprised of medical doctors, audiologists, and acoustical professionals from the United States, Canada, Denmark, and the United Kingdom, the panel undertook extensive review, analysis, and discussion of the large body of peer-reviewed literature, specifically with regard to sound produced by wind turbines. The expert panel was established by AWEA and the Canadian Wind Energy Association (CanWEA) to review all current literature available on the issue of perceived health effects of wind turbines.
“The panel’s multidisciplinary approach helped to fully explore the many published scientific reports related to the potential impact of wind turbines on people’s health,” said Dr. Robert J. McCunney, one of the authors of the study and an occupational/environmental medicine physician and research scientist at the Massachusetts Institute of Technology (MIT). “There is no evidence that the sounds, nor the sub-audible vibrations, emitted by wind turbines have any direct adverse physiological effects on humans.”

Here’s the full study and an executive summary.
