摘要： A device for determining sound source direction includes an array sensor including a plurality of microphones that measures a sound wave, and a processor for calculating a sound pressure in each direction based on sound pressure information of the sound wave obtained by the array sensor and for determining a direction in which the sound pressure is maximum as a direction of sound wave arrival. The plurality of microphones is provided at vertices of two or more concyclic polygons that are on a same plane and that have a same center and are arranged so as to be non-rotationally symmetric as a whole array sensor.
