An acoustical wall panel for use for reduction of sound and noise, including a panel-like structure, formed of a base, generally fabricated of fiberglass, polystyrene, etc., having a covering sheet applied thereon, containing a large number of perforations, to allow noise to pass therethrough, to the sound of absorbing base, the covering sheet being folded over the corners and adhered to itself to provide complete coverage for the side and end edges of the formed panel. A back covering is provided of a foil, polyethylene, or other material, to function as a moisture barrier and protectant for the back of the panel.
