The method involves recording airborne noise generated by the movement of the rotor, and providing an allocation between sections (31,32,33) of the recorded airborne noise. The airborne noise is generated by individual rotor blades, where airborne noise of the rotor blade is compared with the airborne noise of another rotor blade. Noise is transformed into a frequency spectrum and is recorded over time. An independent claim is included for an arrangement for monitoring the area of a wind energy plant. |
