Abstract
In one aspect, a method for controlling the amplitude modulation of the noise generated by wind turbines is generally disclosed. The method may include determining a sound characteristic of a turbine sound wave generated by a wind turbine and generating an additive sound wave based on the sound characteristic such that a resultant sound wave is produced having a peak-to-peak amplitude that is smaller than a peak-to-peak amplitude of the turbine sound wave.
