MONOLITHIC ACOUSTICAL SYSTEM
A composite structure for improving the acoustical properties of a low noise reduction coefficient (NRC) membrane including a sound absorbing layer and a porous, scrim covered, perforated drywall layer. The composite structure comprises outward perforated drywall panels attached to or fixed to inward sound insulation layers or sound absorbing boards. For example, the perforated drywall panels and the rigid sound absorbing panels can be attached together and to an acoustical hard faced substrate such as a drywall ceiling or wall by parallel spaced Z-shaped furring strips. The perforated drywall panels after installation are taped at their edge joints and then painted with a continuous acoustically transparent coating to conceal the perforations and joints and thereby obtain the look of a relatively smooth monolithic ceiling or wall, but with high acoustical properties.
L'invention concerne une structure composite permettant d'améliorer les propriétés acoustiques d'une membrane à faible NRC comprenant une couche d'absorption du bruit et une couche de cloison sèche poreuse, perforée et recouverte de canevas.
