NOISE SUPPRESSION DEVICE

摘要

PROBLEM TO BE SOLVED: To accurately suppress noise components in a configuration utilizing sound signals of a plurality of channels.SOLUTION: A noise suppression unit 32A executes noise suppression processing of suppressing noise components with respect to sound signals xd(t) of D channels generated by a plurality of sound collectors M arranged in different positions. A control unit 34A controls the noise suppression unit 32A so that, with respect to each of a plurality of frequencies, a sound signal xd(t) of a channel in which an average intensity at the frequency is high is preferentially reflected on the noise suppression processing.
