description The invention provides a method of reducing noise emissions of a wind turbine. The method includes receiving data indicative of wind conditions in the vicinity of the wind turbine, and determining an operational set point signal in accordance with a desired operation of the wind turbine, the operational set point signal being determined based on the received data. The method includes applying a perturbation signal to the operational set point signal to obtain a modified operational set point signal, and controlling operation of the wind turbine using the modified operational set point signal to reduce noise emissions of the wind turbine. The perturbation signal is applied such that the modified operational set point signal has greater temporal variation than the operational set point signal.
