Abstract
[Problem] To propose a mechanism capable of performing a noise cancellation process in an ear hole opening type audio processing device. [Solution] An audio processing device including: an audio information acquisition unit that acquires audio information; a holding unit that abuts on a cavum concha or an inner wall of an ear canal and holds the audio information acquisition unit in a space closer to an eardrum side than a tragus, in a state of being worn by a user; an opening portion that opens an ear hole to an outside; and a signal processing unit that generates a noise cancellation signal based on the audio information acquired by the audio information acquisition unit.
