This is a well done graphic, which I find completely ironic because two journalists came to conclusions such as: blades producing pulsing or oscillating sound, flicker can disturb residents, noise produced by vortex shedding, nacelle producing high pitched sound similar to jet engines, all based on information they researched from AWEA and CanWEA.
It’s pretty clear to me that the Wind industry is acknowledging that Wind Turbine NOISE is more than just audible noise measured on a dBA scale, and that the low frequency noise (which, by the way, wind developers do not include in their noise assessments for any gov’t agency regulating Wind development, at least NOT in Ontario) does in fact exist and can penetrate walls and windows.
One small correction should be noted, the blade tip speed is closer to 120 mph, therefore faster than what is noted above.
