ACOUSTIC DEVICE, ACOUSTIC PROCESSING METHOD, AND ACOUSTIC PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To enable the proper suppression of the influence of external noise to reproduction sound.SOLUTION: An acoustic device of an embodiment acquires the frequency characteristics of external noise due to road noise and converts the acquired frequency characteristics of the external noise into hearing sensitivity characteristics according to the frequency characteristics of the hearing sensitivity. The acoustic device sets a parameter according to the hearing sensitivity characteristics to an equalizer. The equalizer corrects the frequency characteristics of an audio signal reproduced in a reproduction unit according to the set parameter.
