发明名称 Method for reproducing sound signals and sound reproducing system
摘要 In a method for reproducing sound signals by means of headphones provided with microphones, unwanted sound signals from at least one external sound source are compensated by sound signals, simulating in anti-phase the sound signals from said at least one external sound source. The anti-phase sound signals being generated in the headphones in response to signals derived from audio input signals of the at least one external sound source in a first filter device which is controlled by the resulting microphone signals. Further, wanted sound signals are generated in the headphones in response to signals derived from further audio input signals in a second filter device with transfer functions substantially equal to the corresponding transfer functions of the first filter device.
