Abstract: A method of controlling airborne tonal noise which originates from a component of a wind turbine, the wind turbine comprising a vibration control system comprising a plurality of actuators. The method comprising identifying a first operating state of the wind turbine; and selecting a first set of one or more of the actuators on the basis of the identified first operating state. Each actuator of the first set is operated to apply a vibration control oscillation to the component in phase opposition to a vibration of the component, thereby damping the vibration of the component and in turn reducing airborne tonal noise originating from the component. A change of the wind turbine to a second operating state is detected, then a second set of one or more of the actuators is selected on the basis of the identified second operating state. Each actuator of the second set is operated to apply a vibration control oscillation to the component in phase opposition to a vibration of the component, thereby damping the vibration of the component and in turn reducing airborne tonal noise originating from the component.
