Acoustic Enclosure is a generally accepted technical term, which is used to define a closed engineering structure, specifically designed and built for the purpose of reduction, minimisation, or attenuation of the noise generated by particular types of equipment or machinery. Such as large air conditioning and refrigeration units, power generators, manufacturing lines, grinders, blowers, compressors, pumps, saw booths, gear boxes, etc. Acoustic enclosures represent a separate type of noise control solutions. Other examples of which are acoustic barriers, screens, louvers, acousticwalls and doors, each specifically designed for a particular application. In the most general situation, acoustic   closures are closed chambers, made of acoustic materials that ensure sound or noise isolation and absorption. Depending on a particular application, acoustic enclosures may also perform additional functions, such as vibration isolation.
