Abstract

A measuring method of the sound field using a high-speed movie of dust was proposed. A sound field generated using two speakers was measured from high-speed movies of dust. Two high-speed cameras and the powered monitor speakers were located. Speaker-L was driven by the sound of Japanese drums and Speaker-R was driven by 80 Hz sinusoidal sound. To analyze the frequency component, generalized harmonic analysis (GHA) was used. From the result of the waveforms and the frequency components, it is confirmed that the sound field information can be obtained from the movement of dust.
