HEADPHONE, ACOUSTIC SIGNAL PROCESSING METHOD, AND PROGRAM

Abstract:

The present invention achieves a headphone that enables mode control for shifting to a conversation mode in which an external sound is output from a speaker without a need to perform troublesome user operation. The headphone includes: a microphone that captures an ambient sound around the headphone; and a mode control unit that controls an output sound of a speaker of the headphone according to a mode. The mode control unit shifts to a conversation mode in which the external or ambient sound is output from the speaker, when detecting utterance of a user wearing the headphone by analysis of an input sound of the microphone. The mode control unit also shifts to the conversation mode, when detecting a touch operation of a prescribed touch type by analysis of an output of a touch sensor array that identifies the type of touch operation on an external surface of the headphone.
