Acoustical sound proofing material and methods for manufacturing same

摘要: An improved acoustical damping wall (ceiling or floor) door material comprises a laminar structure having as an integral part thereof one more layers of viscoelastic which also functions glue and constraining layers, such metal, cellulose, wood, petroleum-based products plastic, vinyl, plastic rubber. In embodiment, standard wallboard, typically gypsum, the external surfaces structure; are fabricated between gypsum exterior. The resulting improves attenuation sound transmitted through structure.
