Abstract
An acoustically absorptive panel comprises a porous acoustical absorber having a planar configuration mounted on a support frame, an acoustically transparent front fabric stretch-mounted on the support frame and spaced from and in parallel alignment with the front face of the porous acoustical absorber and forming an airspace, the porous absorber, front fabric and forward air space acting as acoustical absorbing chamber capable of absorbing a greater range of sound frequencies than the porous acoustical absorber alone, the range of frequencies absorbed depending on the depth of the air space.
