Abstract: A noise reduction system for actively compensating background noise in a noise reduction area in a transport area of a vehicle, the system includes a controller, at least one sensor detecting the background noise of the noise source, a sound generator generating anti-noise and at least one error-microphone to pick up background noise and anti-noise from the sound generator. The system includes sensors for detecting the background noise and are arranged at different positions in the vehicle, wherein each sensor generates a reference signal and the controller comprises a combination unit coupled to the sensors to receive the reference signals, the combination unit determines a virtual reference signal from the reference signals and is coupled to the dynamic adjustment unit in that the virtual reference signal is input to the anti-noise unit, for generating the anti-noise signal on a basis of the virtual reference signal.
