PROBLEM TO BE SOLVED: To accurately recognize a sound source irrelevant to photographing with a camera in a sound source survey device that surveys the sound source on the basis of a sound reception signal obtained by receiving sound emitted from the sound source.SOLUTION: The sound source survey device includes a support member 50 that movably supports a sound source survey probe 30 between a survey position where the sound source probe is disposed for sound source survey and a non-survey position where it is retracted from the survey position, and that movably supports an indicator 40 for indicating the sound source with an optical beam, between an indication position where an exit point of the optical beam is focused on a representative point 30C of the sound source survey probe 30, when the sound source survey probe 30 is disposed at the survey position, and a non-indication position where it is retracted from the indication position. |
