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, ceramics, composites, cellulose, wood, or petroleum-based products such as plastic, vinyl, plastic or rubber.
Claims7
A laminar, sound-absorbing structure for constructing walls, floors, ceilings or doors which comprises:
- a panel capable of attenuating sound, said panel comprising:
- a layer of metal having two surfaces, said layer of metal having a thickness between 0.0048 inches and 0.013 inches;
- a layer of viscoelastic glue on one surface of the layer of metal;
- and
- a layer of a first material selected from the group consisting of plywood, compressed fiber board, oriented strand board (OSB), and medium density fiber board (MDF) over the viscoelastic glue.
A laminar, sound-absorbing structure used for constructing walls, floors, ceilings or doors, which comprises:
- a panel capable of attenuating sound, said panel comprising:
- a layer of metal having two surfaces, said layer of metal comprising non-oiled and regular spackle galvanized steel;
- said layer of metal having a thickness between 0.0048 inches and 0.013 inches;
- a layer of viscoelastic glue on one surface of the layer of metal;
- and
- a layer of a first material selected from the group consisting of plywood, compressed fiber board, oriented strand board (OSB), and medium density fiber board (MDF) over the viscoelastic glue.
A laminar structure used for constructing walls, floors, ceilings or doors comprising:
- a panel capable of attenuating sound, said panel comprising:
- two external layers of a material selected from the group consisting of plywood, compressed fiber board, oriented strand board (OSB), and medium density fiber board (MDF);
- at least one internal metal constraining layer having a thickness that is between 0.0048 inches and 0.013 inches;
- and
- two or more internal layers of a viscoelastic glue separated by the at least one internal metal constraining layer.
A laminar structure used for constructing walls, floors, ceilings or doors comprising:
- a panel capable of attenuating sound, said panel comprising:
- two external layers of a material selected from the group consisting of plywood, compressed fiber board, oriented strand board (OSB), and medium density fiber board (MDF);
- at least one internal metal constraining layer selected from the group consisting of non-oiled and regular spackle galvanized steel, aluminum, titanium and a composite of two or more metals, said internal metal constraining layer having a thickness between 0.0048 inches and 0.013 inches;
- and
- two or more internal layers of a viscoelastic glue separated by the at least one internal metal constraining layer.
