International panel of experts conclude sound from wind turbines has no harmful effect on human health
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
The study’s panel was jointly established by the American Wind Energy Association and
the Canadian Wind Energy Association to conduct a review of all current peer-reviewed
scientific literature available on the issue of perceived health effects of wind turbines.
The objective of the panel was to provide an authoritative reference document for those
making legislative and regulatory decisions about wind turbine developments.
“The Canadian Wind Energy Association supports the responsible and sustainable
development of wind energy in Canada,” said CanWEA president Robert Hornung.
“This study will go a long way in addressing people’s concerns and answering their
questions about the effects of wind turbines. Canada’s wind energy industry will continue
to take a proactive role in ensuring wind energy developments are good neighbours to the
communities that have embraced wind energy.”
