1. A device for measuring a sound source distribution in three-dimensional space, the device comprising:

  • a particle image velocimetry system that irradiates, with laser light, tracer particles included in a flow field around an object at two times that are separated by a very short period of time, and measures a velocity field of three velocity components in three-dimensional space from images at the two times of the tracer particles irradiated with the laser light taken by an imaging device; and

    sound source distribution measuring device that measures a sound source distribution around the object from the velocity field of the three three-dimensional velocity components.
