Multidisciplinary panel conducts most extensive study of its kind to date

OTTAWA, December 15, 2009 – An international panel of experts has released a report based on a review of a large body of scientific literature on sound and health effects, and specifically with regard to sound produced by wind turbines. After extensive review, analysis and discussion, the panel has concluded that sounds or vibrations emitted from wind turbines have no adverse effect on human health.

The study is the most thorough of its kind ever produced by a group of medical or scientific professionals. The seven-member panel includes experts in the fields of medicine, audiology, acoustics, environmental and public health from Canada, the United States, the United Kingdom and Denmark

“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 Massachusetts Institute of Technology. “There is no evidence that the sounds, nor the sub-audible vibrations, emitted by wind turbines have any direct adverse physiological effects on humans.”

  1. Studies may be biased such as the ones by the tobacco companies which showed for about half a century that smoking of cigarettes was not harmful. Such is the case in this study because it is well known that sound can affect the health of sensitive people.
