Abstract
An improved acoustical damping wall (ceiling or floor) or door material comprises a laminar structure having as an integral part thereof one or more layers of viscoelastic material which also functions as a glue and one or more constraining layers, such as metal, cellulose, wood, or petroleum-based products such as plastic, vinyl, plastic or rubber. In one embodiment, standard wallboard, typically gypsum, comprises the external surfaces of the laminar structure; and one or more constraining layers are fabricated between the gypsum exterior. The resulting structure improves the attenuation of sound transmitted through the structure.
Claims18
A laminated structure used for constructing walls, floors, or ceilings or doors comprising:
- two external layers of a non-metallic material,
- at least one internal non-honeycomb constraining layer, and
- two or more internal layers of a viscoelastic glue separated by said at least one internal constraining layer.
A laminated structure used for constructing walls, floors, or ceilings or doors comprising:
- two external layers of a non-metallic material,
- at least one internal constraining layer, and
- two or more internal layers of a viscoelastic glue separated by said at least one internal constraining layer,
- wherein the constraining layer comprises metal.
A laminated structure comprising:
- at least one internal layer of a selected material;
- two internal layers of a viscoelastic glue, one such layer on each side of said internal layer;
- and
- at least one additional layer of a non-metallic material on the other side of each internal layer of viscoelastic glue.
A laminated structure used for constructing walls, floors, or ceilings or doors comprising:
- two external layers of a non-metallic material.
- at least one internal constraining layer, and
- two or more internal layers of a viscoelastic glue separated by said at least one internal constraining layer;
- wherein the at least one internal constraining layer is selected from the group consisting of cellulose, wood, metal, plastic, vinyl, plastic composite and rubber.
