ABSTRACT:
A sound absorptive structure for installation on room wall structure to reduce low frequency wave energy and enhance room acoustics. A fibrous, sound absorptive member is of curved section and terminates in tapered side edges for inserted engagement with wall mounted strips. The structure may be segmented with partitions between the segments. Alternatively T-shaped divider strips may interconnect adjacent segments. A further modification utilizes a flat base for wall attachment with end portions of the base folded perpendicularly to the base to provide closures for the ends of a sound member. Intersections between segments of a sound absorptive structure may be accomplished by corner mounted box structures or may be mitered for endwise abutment with one another. Openings in the room wall structure increase the volume of the present wall mounted structure.
