Abstract
Abstract A novel acoustical wall assembly comprises at least two modular sound absorbing panels. Each panel includes a substantially flat body and an integral tongue extending substantially parallel to and spaced from one edge of the body so as to form a channel therebetween. A double channel connector, comprising first and second U-shaped channel members, is utilized to connect the panels together in a coplanar relation. The side plates of the first channel member fit into the channels of the confronting edges of two modularly aligned panels, and the side plates of the second channel member fit between the panels in tight fitting relationship with the tongues. An L-shaped connector having two side flanges is used to connect the panels together to form a corner wherein the side flanges of the connector fit into the channels of the confronting edges of two adjacent panels. A floor channel member is provided to (a) reinforce the lower longitudinal edges of the panels and (b) secure the panels to the floor, while a ceiling cap is provided to (a) reinforce the upper longitudinal edges of the panels and (b) support ceiling panels.
