<p>A system for processing a sound signal includes a signal receiving device (11), a signal recognising device (12) and a signal processing device (13). The signal recognising device (12) is used to distinguish the sound signal received from the signal receiving device (11) into a sound source signal and background interference, so as to eliminate the background interference and transfer only the sound source signal to the signal processing device (13). In this case, the signal processing device (13) only processes and amplifies the sound source signal and thus no filtering circuit is required for the elimination of the background interference. <IMAGE></p> |
