Abstract
An improved acoustical floor/ceiling, or wall assembly affixed to a support structure, the assembly using laminar panels. A first one of the laminar panels includes a constraining layer of material with a layer viscoelastic glue on the constraining layer and a layer of material of a first composition on the layer of viscoelastic glue. A second one of the laminar panels includes a constraining layer of material with a layer of viscoelastic glue on the constraining layer of material and a layer of material of a composition different than that of the layer of material in the other laminar panel. In one assembly the material in the first laminar panel is cellulose-based material or wood, and the material in the second laminar panel is gypsum board. Constraining layers of material of metal, cellulose-based material, wood and petroleum-based products such as plastic, vinyl or rubber, ceramic, composite are employed.
