The acoustic signal receiving module receives an acoustic signal. The compensator performs compensation on the acoustic signal, as compensation of acoustic characteristics of an ear including an ear canal having a first-order resonance characteristic and a second-order resonance characteristic, to suppress a first-order frequency of ear resonance and a second-order frequency lower than double of the first-order frequency. The output module outputs the acoustic signal compensated by the compensator.

摘要： A common component extraction unit extracts a component Mi(n) included commonly in the plural input channels. A non-common component extraction unit extracts a component Si(n) not common to the plural input channels. A common component noise suppression unit obtains signal Mo(n) by executing a noise suppression process for the component Mi(n). A non-common component processing unit obtains signal So(n) by executing attenuation or emphasis for the component Si(n). A plural-channel generation unit removes noise of the common component from signals In(n, k) of the plural input channels, by using the signals Mo(n) and So(n) such that the non-common component is attenuated or emphasized.
