Abstract
An apparatus and method for detecting sound direction is disclosed, which utilizes a plurality of sound source detecting units to receive a plurality of sound signals form a sound source. The sound source detecting units amplify and filter the sound wave signals to obtain a plurality of amplified sound signals, and transform the amplified sound signals to a plurality of pulse signals for being outputted a processing unit. The processing unit samples the pulse signals to obtain a plurality of sampling signal sequences, and computes a plurality of time differences based on the sampling signal sequences to detect the position of the sound source via looking up a table based on the time differences.
