This paper describes visualizing sound pressure distribution by combining microphone array processing and camera image processing. In microphone array processing, capturing a sound at desired position is achieved by Delay and Sum Beam Forming (DSBF). In camera image processing, taking information of 3D position is achieved by triangulation method with stereo camera. We calculate sound level with capturing sound at 3D position taken by camera image processing. In order to visualize sound pressure distribution, calculated sounds level are superimposed on camera image. Experiments were conducted to examine visualization of sound pressure distribution by using sound level meter for comparing result of sound pressure level.
