A rotor blade with a leading edge and a trailing edge is provided, wherein the rotor blade is designed and configured for being exposed to a fluid flowing substantially from the leading edge to the trailing edge, the rotor blade includes at least two sensors designed for detecting flow characteristics of the fluid and providing respective sensor signals, and the rotor blade further includes at least two actuators for producing an anti-noise signal based on a sensor signal, the sensors are arranged spanwise and the actuators are arranged chordwise at the surface of the rotor blade, and the actuators are arranged and prepared such that flow-induced edge noise of the rotor blade, which is generated by the fluid, is at least partly cancelled out by the anti-noise signal. Also provided is a method for creating such rotor blade and a related wind turbine.
