Abstract
Described are a headphone and a method for controlling an audio system. The method includes tapping a headphone or head of a user to cause an acoustic pressure change in an ear canal of the user wherein the ear canal is sealed by an acoustic noise reduction (ANR) headphone having an ANR module. A current provided to the ANR module is sensed. A peak value of the sensed current is determined and compared to a value of an adaptive threshold to determine if a tap occurred. If a tap is determined to have occurred, an updated value for the adaptive threshold is determined based on the peak value and at least on prior peak value. A mode of operation of the audio system or an attribute of an audio input signal may be changed in response to the determination of an occurrence of a tap.
