SOUND RECEIVING DEVICE, DIRECTIONAL CHARACTERISTIC DERIVING METHOD, DIRECTIONAL CHARACTERISTIC DERIVING APPARATUS AND COMPUTER PROGRAM
摘要：
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.
摘要（中）：

一种具有外壳10的声音接收装置1，其中布置有可以接收从多个方向到达的声音的多个声音接收单元，其包括：全向主音响接收单元11和子声音接收单元12， 接收声音的位置，比从主声音接收单元11接收到声音的时间早一个给定时间，从给定方向以外的方向到达。 对于接收到的声音，声音接收装置计算子声音接收单元11的声音接收时间与主声音接收单元12的声音接收时间之间的时间差作为延迟时间。
