Abstract: An upright space divider panel having a rigid rectangular frame, and first and second thin sheetlike skins fixed to opposite sides of the frame and extending across the region defined therein. A honeycomb core structure is disposed within the frame and confined between the skins. The honeycomb core structure comprises a cellular honeycomb layer having a plurality of cells formed therein and extending across the width of the layer, so that opposite ends of the cells are closed by the skins. The first and second skins are identical and each have a plurality of openings formed therethrough. The openings in the first skin communicate with a first plurality of the cells for forming a first plurality of sound absorbing chambers which open outwardly through one side of the panel. The openings in the second skin communicate with a second plurality of the cells for forming a second plurality of sound absorbing chambers which open outwardly through the other side of the panel.

Abstract: 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.
