ABSTRACT:
A movable, prefabricated wall panel having a rigid rectangular frame, a septum core disposed within the region bounded and confined by the frame, and adjacent layers of fibrous sound absorbing material is disclosed herein. The septum core is formed from a central layer of honeycombed-shaped paper sandwiched between two steel skins, and is fixedly confined to the center of the interior frame perimeter by elongated channels of the perimeter frame. The combined shape forms a central cavity on opposing sides of the septum core allowing relatively thick inner layers of sound absorbing fibrous material, preferably fiberglass, to be placed within the panel adjacent to each steel skin. Outer layers of sound absorbing fibrous material are placed adjacent to the inner layers, and the outer layers are covered with fabric or similar material.
