Variability Factor in Wind Turbine Noise
Summary. Public policy decisions about wind turbine noise face several challenges caused by the “variability factor.” Most sound ordinances are based on an average sound level, while neighbor responses are generally based on shorter-term peak noise levels, along with the additional variability in the sound quality of wind turbine noise; increasingly, complaints arise around projects that meet average sound level criteria. At the community scale, different types of communities may be more or less tolerant of moderately audible wind turbine . . . Complete article »

Wind Farm Noise 2011: Science and policy overview
… Too often, noise complaints are discounted altogether as merely an easy excuse for those who are simply anti-wind, or who don’t like wind turbines in their view. There’s no doubt that some people who are more broadly resisting wind development latch onto the noise issue as one part of their argument, but it’s clearly false to imply that all those with noise concerns are anti-wind. Over and over again, the most compelling testimonies from wind farm neighbors who are . . . Complete article »

Wind Farms and Noise
Clear reports of noise problems up to a mile or so 500 meter / 1500 foot setbacks are often very insufficient NIMBY [not in my backyard]: be careful fears aren’t based on experiences of others in situations not like yours WARYDU [we are right – you don’t understand]: don’t gloss over noise impacts Turbine size and downwind patterns Directionality of amplitude modulation Atmospheric/nighttime conditions What some neighbors are hearing Wind Direction Is Key Can be close with no noise issues, . . .

Wind Energy Noise Impacts
‘Wind energy has long been a favorite of many environmental advocates. No carbon emissions, utilizing a free resource without depleting it in the least, even the potential for distributed generation rather than distant centralized power plants: for many of us, wind was the cleanest of green power sources in our dreams of the energy future. ‘In recent years, as wind turbines have grown from the small backyard kits that the truly committed built in the 70’s, the reality has made . . .
