PROBLEM TO BE SOLVED: To provide a sound analysis method including a transmission path analysis between a sound source within space and an observation position, and to provide a system of the sound analysis system.;SOLUTION: A sound analysis method allows a sound field formed in space to be analyzed. A sound sensor is disposed in an observation position within space, a speaker is moved along a set, virtual sound source surface and a sound particle speed of sound generated from the speaker is measured by a sound particle speed sensor disposed in front of the speaker, and a transfer function acquisition process for acquiring a transfer function between the observation position and its surrounding is included. The sound analysis system includes the sound sensor disposed in an observation position within space, the speaker disposed on a set virtual sound source surface, and the sound particle speed sensor disposed in front of the speaker, the speaker is moved along the virtual sound source surface and a sound particle speed of sound generated by the speaker is measured by the sound particle speed sensor, and the transfer function acquisition part for acquiring a transfer function between an observation position and its surrounding is included.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
