<p>PROBLEM TO BE SOLVED: To achieve noise suppression reducing musical noise without any need of estimation of a noise section.SOLUTION: A noise suppression device 100 includes: a noise estimation section 42 that identifies an estimated noise component N(f,m) for each of a plurality of sub blocks formed by dividing a sound signal x, according to a minimum value of intensity of each frequency of the sound signal x in the sub block; and a noise suppression section 44 that cumulatively repeats noise suppression processing for suppressing the estimated noise component N(f,m) from the sound signal x for each of the plurality of estimated noise component N(f,m) that the noise estimation section 42 has identified for each sub block.</p> |
