MODULAR ACOUSTIC CONFIGURATION FOR CREATING A FLOOR WITH IMPROVED ACOUSTIC INSULATION PERFORMANCES, AND METHOD FOR IMPLEMENTING SAME

摘要

The invention relates to an acoustic configuration (1) for acoustic insulation, with the configuration comprising a floor covering (5) attached to a floating floor with elastic skates (4) resting on a substrate (3) (10), said floating floor comprising skates (4) that are substantially elastic. According to the invention, the floating floor consists of a modular assembly of prefabricated rigid panels (2) with a density of 0.5 to 6, positioned edge to edge with a means of position adjustment that is either male or female, with the skates being homogeneous one-piece elements attached inside the panel, and with the total seat surface ratio Sta of the skates on the substrate on the total surface area Stp of the panel, Sta/Stp being 0.03 to 0.08. In one variant, shims are interposed between the skates and the panel. In the implementation method, a layer of fibrous insulation can be interposed between the substrate and the floating floor.
