Therefore, it is important to observe the of the noise and the vibration caused while equipment is driving, and to detect abnormality of equipment at the stone However even if ahnormality of the sound can be nerceived it is difficult to specifv abnormal parts. The symptom often appears as a sound change before equipment breaks down. Therefore, it is important to observe the state of the nois e and the vibration caused while equipment is driving, and to detect abnormality of equipment at the early stage. However, even if abnormality of the sound can be perceived, it is difficult to specify abnormal parts. Then, we develope d the equipment which search the position of sound source and display visually. In this paper, we explain the principle of the equipment. Keywords: Sound source, Visualization, Frequency, Phase difference, Electro luminescence display
