Abstract

The invention relates to a rotor blade (20) with a leading edge (23) and a trailing edge (24), wherein the rotor blade (20) is designed and configured for being exposed to a fluid flowing substantially from the leading edge (23) to the trailing edge (24) of the rotor blade (20), the rotor blade (20) comprises at least one sensor (31) for detecting flow characteristics of the fluid, and the rotor blade (20) further comprises at least one actuator (32) for producing an anti-noise signal. The sensor (31) and the actuator (32) are both arranged at the surface of the rotor blade (20), and the actuator (32) is arranged and prepared such that flow-induced edge noise of the rotor blade (20), which is generated by the fluid, is at least partly cancelled out by the anti-noise signal. The invention furthermore relates to a wind turbine comprising at least one such rotor blade (20).
