  • Noise suppression system and method therefor
    Patent number: 5544250
    Abstract: A noise suppression system (105) and method therefor includes a signal gain calculator (205) for calculating a constant gain value (701) for an input signal (116) according to a first function (703) responsive to a noise energy estimate (213) and a signal to noise ratio (SNR) estimate (215) until the SNR estimate (215) reaches a first predetermined SNR threshold (705), then calculating a variable gain value (707) for the input signal (116) according to a second function (709) responsive to the noise energy estimate (213) and the SNR estimate (215) until the SNR estimate (215) reaches a second predetermined SNR threshold (711) below the first predetermined SNR threshold (705), then calculating the constant gain value (701) responsive to the noise energy estimate (213) and the SNR estimate (215) when the SNR estimate (215) reaches the second predetermined SNR threshold (711).
