There’s a Persistent Hum in This Canadian City, and No One Knows Why
Author: Mele, Christopher
A persistent noise of unknown origin, sometimes compared to a truck idling or distant thunder, has bedeviled a Canadian city for years, damaging people’s health and quality of life, numerous residents say. Those who hear it have compared it to a fleet of diesel engines idling next to your home or the pulsation of a subwoofer at a concert. Others report it rattling their windows and spooking their pets. Known as the Windsor Hum, this sound in Windsor, Ontario, near . . .
More »Rigorous Method of Addressing Wind Turbine Noise
Author: Palmer, William
Numerous papers, including some by this author, have identified what are dismissed with disdain as “anecdotal reports” of adverse impacts that occurred with the start up of wind turbines in the environment of those impacted. However, there is a solid basis for presenting such lists. It mirrors the approach taken by most medical doctors when a patient first presents himself or herself with a new adverse health complaint. Taking a patient “history” is the way most doctors begin. Similarly, engineers . . .
More »Bat Mortality Due to Wind Turbines in Canada
Author: Zimmerling, Ryan; and Francis, Charles
ABSTRACT: Wind turbines have been hypothesized to affect bat populations; however, no comprehensive analysis of bat mortality from the operation of wind turbines in Canada has been conducted. We used data from carcass searches for 64 wind farms, incorporating correction factors for scavenger removal, searcher efficiency, and carcasses that fell beyond the area searched to estimate bat collision mortality associated with wind turbines in Canada. On average, 15.5 ± 3.8 (95% CI) bats were killed per turbine per year at these sites (range . . .
More »Considerations regarding an acoustic criterion for wind turbine acceptability
Author: Palmer, William
Introduction. A common regulatory acceptance criterion for wind turbine installation in Canada is that sound pressure level does not exceed 40 dBA outside a home when the wind speed at 10 metres elevation does not exceed 4 metres per second. A clue to the ineffectiveness of this criterion can be seen from over 2700 complaints filed in Ontario with regulators by residents living in homes where acoustic conditions were predicted in approved models to comply with the current criterion. Residents . . .
