Classification: CPC H | IPC H

Claim 15:
16. The method of claim 15, wherein reducing the dynamic range of the second audio signal within the predefined frequency range includes:
initiating amplitude suppression of the second audio signal upon detecting that (i) an amplitude of the second audio signal exceeds a second threshold for a first predefined time period and that (ii) the second audio signal includes at least one frequency component within the predefined frequency band during the first predefined time period; and
turning off the amplitude suppression of the first band-pass filtered audio signal upon detecting that (i) the amplitude of the second audio signal is below the second threshold for a second predefined time period or that (ii) the second audio signal does not include frequency components with the predefined frequency band during the second predefined time period.
