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 16):
The system of  claim 12 , further comprising an input device configured to receive a user input, wherein the pre-indicated approximate sound pressure level of the speech component is based at least in part on the received input, wherein the pre-indicated approximate sound pressure level is either at a first level or at a second level, wherein the first level corresponds to a situation where the speech component is at a sound pressure level of average conversational speech, wherein the second level corresponds to a situation where the speech component is at a sound pressure level of lower than that of average conversational speech, wherein the sound pressure level of average conversational speech is approximately 60 dB.
