Abstract

A method and an apparatus for monitoring an acoustic emission of a wind turbine that includes a rotor blade. The apparatus includes at least one sensor operatively coupled to the wind turbine. The sensor is configured to detect an atmospheric condition. A control system is communicatively coupled to the sensor, and configured to control operation of the wind turbine to adjust the acoustic emission of the wind turbine based on the atmospheric condition.
