Abstract:
A method of adaptive noise cancellation can include receiving an audio input signal, receiving an ambient signal through a microphone, modifying filter parameters of a noise filter based on the ambient signal, and filtering the audio input signal based on the modified filter parameters.

Claim (Index 4):
An adaptive gain system, comprising:\n a speaker; a feedback microphone configured to sample the speaker; a feed-forward microphone configured to sample a listening environment; a controllable amplifier electrically coupled between the feed-forward microphone and the speaker; and an adaptivity controller electrically coupled with the controllable amplifier and configured to control the controllable amplifier based at least in part on output from the feedback microphone and output from the feed-forward microphone.
