摘要： A wind turbine blade, comprising a sensor device for detecting properties of flow-induced noise produced by the blade and an actuator device for emitting an anti-noise signal for at least partially cancelling out the flow-induced noise, wherein the actuator device comprises an aerodynamically shaped housing attached to an outer surface of the blade. The aerodynamically shaped housing of the actuator device reduces a deterioration the aerodynamic efficiency of the blade. Further, the generation of turbulences at sharp edges of the housing is avoided.
