ACOUSTIC DEVICE, ACOUSTIC PROCESSING METHOD, AND ACOUSTIC PROCESSING PROGRAM

摘要

In an embodiment of this acoustic device an acquisition unit obtains the frequency characteristic of outside noise caused by road noise or the like, and a conversion unit converts the obtained frequency characteristic of the outside noise to an auditory sensitivity characteristic in accordance with an auditory sensitivity frequency characteristic. A setting unit of this acoustic device sets in an equalizer (12) a parameter (401) that is in accordance with the auditory sensitivity characteristic. In accordance with the parameter that has been set by the setting unit, the equalizer corrects the frequency characteristic of an audio signal reproduced by a reproduction unit (10).
