Patent ID: 8849231

Claim:
A method for providing adaptive power control, comprising: receiving a primary acoustic signal having a plurality of components including a noise component, the primary acoustic signal representing at least one captured sound; performing frequency analysis on the primary acoustic signal to generate a plurality of frequency sub-bands; estimating a power level of the noise component of the primary acoustic signal, the estimating of the power level occurring in at least one frequency sub-band of the primary acoustic signal, the estimating of the power level comprising tracking the energy of the at least one frequency sub-band of the primary acoustic signal; comparing the power level to at least one noise threshold; and controlling a noise suppression system based on the comparison of the power level to the at least one noise threshold, wherein the noise suppression system is configured to be powered on and off based on the comparison; wherein controlling the noise suppression system comprises providing continuity in an output signal when the noise suppression system is powered on or off by preserving a non-zero latency introduced by the noise suppression system.
