The wind turbine in a wind farm can produce Amplitude Modulation Noise (AMN) is known to be caused by rotating airfoil self-noise particularly trailing edge scattering noise and Doppler effect due to blade motion relative to observer, it is also recognized as Swish sound. Envelop of the acoustic wave appeared to be blade passing frequency; therefore it gives people impression that it is Low Freque...
