摘要
A noise-cancellation system for a headphone (HP) that comprises a speaker (200, 210) for emitting a speaker signal, a microphone (300, 310, 320, 330) for receiving a microphone signal and a proximity sensor (400, 410) for a receiving a proximity signal comprising quantitative information on the distance of the an object (OBJ) from the proximity sensor (400, 410) has a signal processing device (100). The signal processing device (100) is designed to generate a compensation signal based on the microphone signal, wherein the generation of the compensation signal comprises filtering with an adjustable filter characteristic. The compensation signal is combined with an audio signal in order to generate the speaker signal. The filter characteristic is adapted based on the distance.
