Abstract

A method of blade pitch control actuation, which reduces rotor noises during operation of a wind turbine. A microphone or a blade mounted pressure sensor provides a noise level feedback signal to a blade pitch controller. The blade pitch controller uses the feedback signal to adjust the blade pitch to reduce the measured noise decibel level to an acceptable decibel level.
