Abstract: A method for reducing noise generated by a wind turbine includes measuring a reference temperature of the wind turbine. The method also includes regulating a trailing edge surface temperature of a trailing edge portion of a rotor blade attached to the wind turbine. In addition, the method includes measuring the trailing edge surface temperature. Further, the method includes regulating the trailing edge surface temperature to maintain a predetermined temperature differential between the reference temperature and the trailing edge surface temperature.
