Abstract

Health Canada developed a technique, to derive a noise criterion of 45dBA, as the level at which mitigation is recommended for wind turbines operating in quiet rural areas. This criterion is intended to avoid rattles, sleep disturbance, and an increase in %HAn greater than 6.5%. Health Canada has recommended that noise mitigation be considered, when a project-related long-term increase in the calculated %HA exceeds 6.5%, based on the characterization of a severe noise impact in a report developed by a team of researchers for the US Department of Transportation. Additional rationales for using a change of 6.5% in the %HAn have also been reviewed by some other researchers.
