Abstract:
A method for reducing noise within an acoustic signal includes receiving at least a primary acoustic signal from a primary microphone and a secondary acoustic signal from a different, secondary microphone, wherein the primary acoustic signal includes a speech component emanating from a user and a noise component. The method also includes measuring a first value of a first coefficient based on the primary and secondary signals and performing a noise cancellation process based on the measured first value of the first coefficient to produce a set of noise-cancelled primary sub-bands. The method also includes generating, by the processor, a set of multiplicative gain mask values, the multiplicative gain mask values having a frequency dependency that is based at least in part on a pre-indicated approximate sound pressure level of the speech component.

Claim (Index 13):
The system of  claim 12 , further comprising:\n a gate generator module configured to:\n determine an estimated energy level of the noise component; and \n generate a set of multiplicative noise gate values to be applied to a subset of the primary sub-bands falling below an energy threshold that is at least as high as the estimated energy level, wherein the signal modifier is further configured to apply the multiplicative noise gate values to the subset of noise-cancelled primary sub-bands.
