Sound source locating system and method

The invention relates to a sound source positioning system and a sound source positioning method. The sound source positioning system comprises microphones and calculating units, wherein, each microphone respectively senses a target sound source so as to output time domain signals. The calculating units respectively transform all the time domain signals into frequency domain signals and carry out intersectant frequency spectrum calculus according to each frequency domain signal so as to obtain the time differences of arrival and determine the position of the target sound source according to each time difference of arrival and the position of each microphone.
