PROBLEM TO BE SOLVED: To identifiably display the correctly estimated incoming direction of a sound and the incorrectly estimated incoming direction of a sound. SOLUTION: A system 100 for determining the incoming direction of the sound estimates the incoming direction of the sound by a sound source position estimation part 24 of a calculation processing part 23 of a personal computer 20 from the arrival time difference of the sound to each microphone of a measurement unit 10. A false sound source position determination part 25 determines the believability of the estimated incoming direction of the sound. A display processing part 26 identifiably displays on a display 29 the sound source position determined to be low in believability and the sound source position determined to be high in believability at the same time.
