Abstract
A method of masking tonal noise from a wind turbine. The wind turbine has a noise generator and a rotor-nacelle-assembly (RNA). The RNA comprises a nacelle and a rotor configured to rotate about a rotor axis with a horizontal projection. The method comprises: feeding a drive signal into the noise generator so that the noise generator emits directional masking noise, wherein the directional masking noise at least partially masks tonal noise from the wind turbine and points in a masking direction with a horizontal projection. The horizontal projection of the masking direction points away from the horizontal projection of the rotor axis.
