Abstract
A signal processing technique the noise suppressing performance of which is more improved than conventional one is provided. A first component extraction unitextracts a non-stationary component ^φ(ω, τ) derived from a sound coming from a target area and a stationary component ^φ(ω, τ) derived from an incoherent noise from a power spectrum density ^φ(ω, τ) of the target area through processing of time average. A second component extraction unitextracts a non-stationary component ^φ(ω, τ) derived from an interference noise and a stationary component ^φ(ω, τ) derived from an incoherent noise from a power spectrum density ^φ(ω, τ) of a noise area.
