PROBLEM TO BE SOLVED: To provide a method and an apparatus for determining a sound source direction capable of determining a plurality of similar sound source directions such as voices of a plurality of people. SOLUTION: The sound source direction determining apparatus 10 for specifying an arrival direction of a sound based on acoustic signals of two channels obtained by two microphones 11 and 12 arranged at a predetermined interval comprises a phase difference spectrum generating means 15 for obtaining a phase difference spectrum due to the acoustic signals of two channels, a power spectrum generating means 16 for obtaining a power spectrum of at least one of the acoustic signals of two channels, and a sound source direction specifying means 17c for determining the sound source direction every sound source based on the phase difference spectrum and the power spectrum.
