The Acoustic Imaging Camera combines acoustic images with video footage captured by a camera mounted on a microphone array, presenting a transparent overlay that allows for intuitive analysis of the tested object's condition. Utilizing acoustics, electronics, and information processing technology, this technique transforms sound into visible images, aiding users in comprehensively understanding sound fields, waves, and sources. It facilitates easy identification of the origins and causes of noises and vibrations in machinery, reflecting the operational stateof the device.
