Abstract
An acoustic device includes binaural speakers, a storing portion for storing a plurality of head-related transfer functions, and a signal processing portion for processing a sound signal with a head-related transfer function. Two or more function candidates are selected from the plurality of head-related transfer functions. Prescribed test sounds are emitted from the speaker. A function candidate to apply to the user is selected based on a discrepancy between a user-perceived location direction and the sound generation location direction for each function candidate.
