A sound receiving device 1 having a housing 10 in which a plurality of sound receiving units which can receive sounds arriving from a plurality of directions are arranged, includes an omni-directional main sound receiving unit 11 and a sub-sound receiving unit 12 arranged at a position to receive a sound, arriving from a direction other than a given direction, earlier by a given time than the time at which the main sound receiving unit 11 receives the sound. With respect to the received sounds, the sound receiving device calculates a time difference, as a delay time, between the sound receiving time of the sub-sound receiving unit 11 and the sound receiving time of the main sound receiving unit 12.
