Abstract

An exemplary sound reproducing, noise reducing method and system include supplying to a corresponding loudspeaker a useful signal that represents sound to be reproduced and an anti-noise signal that, when reproduced by the corresponding loudspeaker, reduces noise in the vicinity of the corresponding microphone. The method and system further include receiving audio input signals and processing the audio input signals to provide the useful signals so that the useful signals provide a more realistic sound impression for a listener wearing the helmet than the audio input signals.
