Wind Turbine Noise
The reliance on wind as a source of energy is increasing in Canada and around the world. Some residents in communities that host large-scale turbine electricity generators have reported adverse health effects which they attribute to the sound emitted by operating wind turbines.
Health Canada provides advice on the potential health impacts of environmental noise, including that from wind turbines, which is protective of health. This advice is based on research, reviews of the scientific literature, World Health Organization guidelines, international standards, and knowledge gained from environmental assessments.
Wind Turbine Noise and Health Study
Health Canada, in collaboration with Statistics Canada and other external experts launched a multi-year research study in July 2012 to explore the relationship between exposure to sound levels produced from wind turbines and the extent of health effects reported by, and objectively measured in, those living near wind turbines.
The research design for the study was posted for a 60-day comment period to allow for public review and input. Feedback obtained through the consultation, as well as the responses provided by Health Canada officials, was compiled and posted on the Department's website in alignment with transparent business practices.
Health Canada has released a summary of the results of the study. Results should only be considered final following peer review and publication in the scientific literature. The results of this study contribute to the body of peer-reviewed scientific research on wind turbine noise, but do not provide definitive answers on their own.
