Abstract
In this paper, we aim at development of the measuring device which can measure 64 points at the same time, and measurement of sound pressers at hundreds of thousands points with the device. In order to prove the effect of the loudspeaker arrays system, it is necessary to visualize sound spots. The following two functions are included in the developed measuring device in order to realize the purpose. One is "multiple points coincidence measurement function" which can measure multiple points in one-time measurement, in order to carry out acoustic field measurement for a short time. And another is "autonomous move function" which a measuring device can move automatically to the arbitrary request place. In order to prove the usefulness of the developed measuring device, the sound pressure distribution measurement experiment of an acoustic field is conducted.
