Abstract
A noise control enclosure comprises an assembly of a plurality of panels each having a structural framework on which a sound deadening sheet material is affixed. The structural framework is formed of frame members which have mounting flanges which are disposed about the periphery of the structural framework of each panel. The sound deadening sheet is permanently affixed thereto, for example by a suitable adhesive. Individual panels are removably connected to each other to form the enclosure by fastening means such as self-tapping screws. The sheet material is interposed between abutting frame members of adjacent panels. Peripheral edges of the sheets mounted on the framework or strips of similar material extend between abutting frame members of the structural framework to provide acoustic sealing between panels. The individual panel construction permits on site assembly and disassembly.
