Abstract:
A system that performs noise estimation for an audio adjustment application comprises a coherence calculator that determines at least one coherence value between microphone signals generated by at least two microphones that each independently senses acoustic energy in a listening space. A first microphone of the at least two microphones generates a first microphone signal from the acoustic energy and a second microphone of the at least two microphones generates a second microphone signal from the acoustic energy. The acoustic energy comprises a combination of an audio signal transduced by one or more speakers and environmental noise of the acoustic energy that is local to the listening space. A noise estimate computation processor determines an estimate of a level of the environmental noise based on the at least one coherence value.

Claim (Index 13):
The method of  claim 10 , wherein the coherence calculator comprises a plurality of coherence calculators, wherein each of the plurality of coherence calculators includes two inputs for communicating with the first and second frequency analyzers, respectively, and wherein the method further comprises:\n receiving, by the two inputs of each coherence calculator of the plurality of coherence calculators, a frequency band of the first and second plurality of frequency bands; and generating, by each coherence calculator, a coherence value of the coherence values in response to a comparison of the frequency band received at each of the two inputs.
