Sound absorbing panel

摘要

A movable, prefabricated wall panel having a rigid rectangular frame. A core structure is disposed within the region bounded by the frame, which core structure comprises at least one honeycomb layer. Sheetlike skins are fixedly secured to opposite sides of the frame and extend across the region bounded by the frame for confining the honeycomb layer therebetween. A plurality of small openings are formed in either or both of the skins so that approximately a single opening will communicate with a single cell as defined by the honeycomb layer. The opening and the cell are of a preselected size so as to function as a sound absorbing chamber. The sheetlike skins are also covered by a layer of fibrous sound absorbing material, preferably fiberglass.
