A glass wool panel, intended to be used as an acoustic panel, has a density of less than or equal to 130 kg/m, an air flow resistivity of between 30 and 120 kPa&#xb7;s/m, a Young's modulus of between 0.5 and 4 MPa.

Glass wool acoustic panel and process for manufacturing such a panel

A building element includes a sheet of a rigid material and at least one nonlinear energy sink including a blade with two end parts and a nonlinear spring function intermediate part, a mass fixed to the nonlinear spring function intermediate part of the blade, and a fixing element allowing the two end parts of the blade to be fixed to a solid support in such a way that the nonlinear spring function intermediate part can oscillate about its position of equilibrium or its positions of equilibrium. The nonlinear energy sink is fixed rigidly to the sheet by the fixing element. The building element can be contained in a partition wall. Additionally, such an energy sink or building element can be used for reducing the acoustic transparency of a wall.

Non-linear dynamic absorber and use thereof for acoustic insulation

A multilayer sound-absorbing covering includes (a) a support layer made of an organic polymer foam having an open porosity between 0.50 and 0.995, (b) a surface layer formed by a glass textile, having a static air flow resistance, measured according to the standard ISO 9053, between 105 N&#xb7;s&#xb7;m-4 and 106 N&#xb7;s&#xb7;m-4, (c) at the interface between the support layer (a) and the surface layer (b), a discontinuous adhesive layer having a surface density between 17 and 60 g/m. There is also provided a process for manufacturing such a covering and the use of such a covering for improving the acoustic comfort of a room or of a building.

Acoustic absorbent wall coating

A multilayer sound-absorbing covering includes (a) a support layer made of a nonwoven based on organic fibers having a tranverse multilobal cross section, (b) a surface layer formed by a glass textile, having a static air flow resistance, measured according to the standard ISO 9053, between 10N&#xb7;s&#xb7;mand 10N&#xb7;s&#xb7;m, (c) at the interface between the support layer (a) and the surface layer (b), a discontinuous adhesive layer having a surface density between 17 and 60 g/m. There is also provided a process for manufacturing such a covering and to the use of such a covering for improving the acoustic comfort of a room or of a building.
