Abstract
A noise suppression device includes an input signal analyzer that analyzes the harmonic structure and periodicity of a plurality of input signals on the basis of power spectra of a plurality of input signals, a power spectrum synthesizer that synthesizes the power spectra of the plurality of input signals to generate a synthesized power spectrum according to the result of the analysis by the input signal analyzer, a noise suppression amount calculator that calculates an amount of noise suppression on the basis of the synthesized power spectrum and an estimated noise spectrum estimated from the input signals, and a power spectrum suppressor that carries out noise suppression on the synthesized power spectrum by using the calculated amount of noise suppression.
