Disclosed herein is a high density sound transmission loss panel for constructing soundproof enclosures. Each panel is comprised of a steel base and side plates, a layer of concrete which is disposed between the side plates and anchored to the base plate, a layer of sound absorbing materials disposed over the concrete and an interior perforated sheet which is positioned over the sound absorbing material and affixed to the interior ends of the side plates. Adjacent panels are secured together to form enclosures by welding of otherwise securing together the side plates of adjacent panels to form sound type joints therebetween.
