Microphone Array System for Noise Source Identification
Noise source identification of large-scale machinery is a tough issue. If you don’t know the noise source, you cannot find out methods of improving you products. Microphone array, or acoustic camera, is an advanced technology for noise source identification in steady, non-steady, motion, or rest state. A microphone array system can display noise source distribution in real time, and identify the locations of noise source inside the equipment.
