Acoustic camera : ウィキペディア英語版 | Acoustic camera An acoustic camera is an imaging device used to locate sound sources and to characterize them. It consists of a group of microphones — also called microphone array — that are simultaneously acquired to form a representation of the location of the sound sources. == Terminology == The term acoustic camera has first appeared at the end of the 19th century: A physiologist, J.R. Ewald, was investigating the function of the inner ear and introduced an analogy with the Chladni plates (a domain nowadays called Cymatics), a device enabling to visually see the modes of vibration of a plate. He called this device an acoustic camera. The term has then been widely used during the 20th century to designate various types of acoustic devices, such as underwater localization systems or active systems used in medicin. It designates nowadays any transducer array used to localize sound sources (the medium is usually the air), especially when coupled with an optical camera.
