ACOUSTIC PROCESSING DEVICE, ACOUSTIC PROCESSING METHOD AND ACOUSTIC PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an acoustic processing device capable of improving noise suppression performance, an acoustic processing method and an acoustic processing program.

SOLUTION: A storage part stores operation data showing operation of an apparatus and an acoustic feature amount in the operation in association with each other; a noise estimation part estimates an acoustic feature amount of a noise component on the basis of an acoustic feature amount of an inputted acoustic signal; an acoustic feature amount processing part calculates a target acoustic feature amount in which the noise component is removed on the basis of the acoustic feature amount of the inputted acoustic signal and the acoustic feature amount of the noise component estimated by the noise estimation part; and an update part updates the acoustic feature amount stored in the storage part on the basis of the inputted operation data and the acoustic feature amount of the noise component estimated by the noise estimation part.
