An acoustic camera is the equivalent of a thermal camera for noise! <\/p>\n\n\n\n

“It’s an imaging device used to locate sound sources and to characterize them. It consists of a (large) group of microphones, also called a microphone array, from which signals are simultaneously collected and processed to form a representation of the location of the sound sources.”(WiKi)<\/p>\n\n\n\n

You point it at an area and the software (based on beamforming) will perform complex calculations from the info of the 128 channels to show the user where the loudest sound source is.<\/p>\n\n\n\n

Imagine a refinery as here below in the picture, there are hundreds of sound sources causing noise nuisance, but with a sound level meter you will only be able to measure the overall sound pressure level in Decibel.<\/p>\n\n\n\n

Sound source positioning challenge for refinery, hundreds sound sources, how to find the loudest one ?<\/figcaption><\/figure>\n\n\n\n

When we put the acoustic camera on some distance of the refinery, we will directly find the loudest sound source. If we need more detail, we can even see the sound level of only this sound source!! This is impossible with traditional sound level meters. The video here below will give you an idea how it works.
