Abstract
A microphone array () having microphones () observing sound and a noise elimination processing unit () obtaining a sound of interest by eliminating noise from the observed sound signal are provided. The two microphones () which are adjacent to each other from among the plurality of microphones () have a positional relationship in such a manner that, in a plane () including the two microphones (), a sound-of-interest source (A) generating a sound of interest, and a noise source (B) generating noise, the perpendicular bisector () of a first line segment () connecting the two microphones () coincides with the bisector of the angle θ between a second line segment () connecting the sound-of-interest source (A) and the midpoint () of the first line segment () and a third line segment () connecting the noise source (B) and the midpoint () of the first line segment ().
