摘要： PROBLEM TO BE SOLVED: To provide a sound source identification apparatus for identifying a vehicle or a sound source generating a sound higher than a specified one, which can exactly identify sounds in a low sound area and those in a high sound area.
SOLUTION: The sound source identification apparatus includes: a first sound source calculation part that calculates a sound source position by beam forming calculation based on a first sound signal indicating a sound component in a sound area subjected to high-frequency extraction extracted from an original sound signal obtained by receiving a sound emitted from a vehicle running on a vehicle traffic road; a second sound source calculation part that calculates a sound source position by acoustic intensity calculation based on a second sound signal indicating a sound component in a sound area subjected to low-frequency extraction extracted from an original sound signal; and a sound source identification part that identifies a sound source based on the sound source position calculated by the first sound source calculation part and the sound source position calculated by the second sound source calculation part.
