Abstract
A method and apparatus for acoustic noise cancellation ('ANC') in an audio headset. A combination of an analog feedforward path and at least one digital feedforward path enables the ANC facility to operate with the shorter delay inherent in analog electronics, but with the capability of better cancellation of reflections that digital feedforward allows.
