ABSTRACT:
An acoustical control media includes an air impervious septum adjacent which there is positioned a relatively thick layer of low density filler material on the outside of which there is provided a relatively thin panel of medium density perforated material. The acoustical media so formed can be used in acoustical panels employed to separate work areas in an office and in such applications decorative coverings can be provided over the perforated layer. The structure so formed provides improved broad bandwidth absorption of acoustical energy.
