ABSTRACT:
An acoustic panel having highly desirable sound absorption characteristics. The panel is preferably formed of an open frame, there being at least one septum centrally located within the frame opening and in contact with the frame members. On each side of the septum are expanded fiberglass batts. Both sides of the frame are faced with perforated hardboard sheets which, in turn, are covered by an open-cell foam layer and a layer of scrim material comprising metal foil and a tear-resistant backing. The panels can be covered with a decorative fascia such as fabric or synthetic sheet materials.
