1. A noise suppression circuit for use in an audio signal processing circuit, the noise suppression circuit comprising:

  • a plurality of different types of noise activity detectors each adapted for detecting the presence of a different type of noise in a received signal; and

    a plurality of different types of noise reduction circuits each adapted for removing a different type of detected noise, where each noise reduction circuit respectively corresponds to one of the plurality of noise activity detectors;

    wherein when each one of the plurality of noise activity detectors detects the presence of a corresponding type of noise in the received signal, the respective noise reduction circuit is selectively activated to condition the received signal to reduce the amount of the detected types of noise.
