ABSTRACT:
An acoustical wall panel for mounting on walls or similar surfaces includes a wooden support frame, low density fiberglass batts positioned within the support frame, and a generally rigid acoustical board positioned in front of and against the frame. A sheet of material is attached to the back of the frame to hold the fiberglass batts in place. The fiberglass batts and acoustical board are selected so that the batts effectively absorb acoustical energy at one end of the frequency spectrum while the acoustical board absorbs acoustical energy at the other end of the spectrum. An acoustically transparent fabric is positioned over the front surface of the acoustical board to extend over the edges of the board and support frame to the back of the frame where the fabric is attached through the sheet of material to the frame. The fabric serves to hold the acoustical board and support frame together. A mounting frame is provided for mounting the assembled acoustical wall panel to a wall or similar surface. The mounting frame and support frame include fastening elements which mate and detachably hold together when the support frame is inserted into the mounting frame.
