    Abstract

    In this paper, we propose a measuring method of the sound field from high-speed movie of dust. The movements of dust in the sound field are affected by the sound vibration. We observe the dust using high-speed cameras. The movie is recorded by one high-speed camera in order to get the information of 2-D sound field and two high-speed cameras for 3-D. The influence of air current is reduced from the movement of dust so that the sound field information is extracted. The experimental results indicate that this method is effective to observe the sound field especially composed of low frequency components.
