摘要： Disclosed is a differential microphone unit which can improve the characteristics of a microphone unit and widen the directional range thereof. The disclosed differential microphone unit (100) is provided with: a microphone housing (20) which is provided with a pair of first sound holes (22a, 22b) on the same major surface (20a); a vibrating portion (11) which is disposed in the microphone housing and which vibrates according to differences in sound pressure transmitted via each of the pair of first sound holes; and sealing members (30, 130), which are disposed on the major surface of the microphone housing and which each contain a pair of second sound holes (31a, 31b, 131a, 131b) disposed so as to be in respective contact with the pair of first sound holes. The opening length (L3) of the pair of second sound holes, which are in the sealing members on the opposite surface to the microphone housing side thereof, in a second direction perpendicular to a first direction in which the first sound holes are aligned, is larger than the opening length (L1) of the first sound holes in the second direction, which are on the major surface of the microphone housing.

摘要： A sound separating device includes a first microphone that converts input sound into a first sound signal, a second microphone that converts input sound into a second sound signal and has characteristics of a larger distance attenuation ratio than the first microphone, and a sound signal processing portion that optimizes a separating matrix by independent component analysis based on the first sound signal and the second sound signal that are supplied, and uses the optimized separating matrix so as to separate a third sound signal as a sound signal from a near field sound source and to separate a fourth sound signal as a sound signal from a far field sound source.
