Acoustics of infrasound and audible noise inside homes near wind turbines using multichannel spectral processing
Abstract
Previous measurements inside homes show presence of BPF’s (Blade Pass Frequencies) below 10Hz as far away as 120km from the nearest Wind Turbine. This holds true for measurements inside homes, yet outside measurements become more challenging at all frequencies due to Wind Turbulence. Random wind turbulence occurs at the microphone screening devices as well as adjacent structures predominantly at lower frequencies. The homes, both near and far, act as windscreens in these low frequency settings, un-masking the BPFs that appear inside. This paper discusses both near and far field measurements in different locations inside homes while making simultaneous spectral measurements outside. Measurements inside, being free from wind turbulence, indicate BPF’s are clear and distinct below audible levels at all times of day and year.
