Abstract: A method performed by an audio system that includes a headset. The method identifies a cushion that is coupled to a headset housing of the headset in which a speaker is integrated therein, produces a reference microphone signal from a reference microphone of the headset, selects an active noise cancellation (ANC) filter based on the identified cushion, filters the reference microphone signal with the ANC filter to produce an anti-noise signal, drives the speaker with the anti-noise signal, in response to driving the speaker, produces an error microphone signal from an error microphone of the headset, and performs an adaptive ANC function to adapt the ANC filter based on the reference microphone signal and the error microphone signal.
