A visualization method of sound intensity measurement of the reflected sound in enclosed space was investigated. The method used photographs of the enclosures. The combination of images of the sound field and the measurement results which is often used in noise source identification systems is an essentially intuitive method. Some photographs covering all directions were taken with the digital cameras. The photos were then switched to create an on-sheet panorama photo. The generated photo was then pasted onto the surface of a transparent sphere. It was found that the method could significantly improve the intelligibility of the direction of arrival of the reflections.
