Abstract
Abstract A hanger is disclosed for supporting sound absorption panels wherein the panels have a top frame member with a depending lip portion. The hanger has a horizontal portion and a vertically downwardly depending portion, with the vertically downwardly depending portion having an upwardly and inwardly formed portion which can engage the depending lip of the frame of the panel to support the panel while the horizontal portion of the hanger is attached to supporting means. The formed portions can be useful in holding together abutting panels. A horizontally movable sound absorption wall is disclosed having one or more sound absorption panels supported by a top frame member, a hanger attached to the top frame member, and a track and guiding means for guiding the hanger along the track.
