FAS 10 Noise from wind turbinesBritish Wind Energy Association
The new studies find that night-time 'swoosh' sound—technical referred to as 'amplitude modulation' (AM)—from wind turbines is likely to be heard by neighboring residents up to five times more often than during day-light hours, depending onwind direction, season and wind farm distance. For...

2 Noise Emission for Ampair 600 4.4m/s wind speed An Alternative Approach Another way of looking at the noise generated by the proposed turbine is to examine the variation with wind speed of the power level of some commercially available turbines and the 45dB distance. The turbine data was ...
Wind turbines emit low frequency noise (LFN) and large turbines generally generate more LFN than small turbines. The dominant source of LFN is the interaction between incoming turbulence and the blades. Measurements suggest that indoor levels of LFN in dwellings typically are within recommended guide...
Similarly to large wind turbines (Re=ΩDc/(2ν)>106), under free-stall conditions, the dominant noise source is expected to be broadband trailing edge noise. In contrast, the dominant noise source at high flow rate coefficients comes from the fluctuating aerodynamic blade force due to large ...
