1. 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 visco
1. 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; anda 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. 2. The laminar, sound-absorbing structure of claim 1 wherein the metal layer comprises non-oiled galvanized steel. 3. 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; anda 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. 4. 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; andtwo or more internal layers of a viscoelastic glue separated by the at least one internal metal constraining layer. 5. Structure as in claim 4, wherein the two or more internal layers of glue comprise a viscoelastic material capable of absorbing sound and vibration. 6. Structure as in claim 4, wherein the at least one internal metal constraining layer comprises non-oiled galvanized steel. 7. 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; andtwo or more internal layers of a viscoelastic glue separated by the at least one internal metal constraining layer.
