  • Acoustic fibrous decoupler
    Patent number: 11633944
    Abstract: Moulded three-dimensional noise attenuating trim part for a vehicle, comprising at least a three layer system consisting of a first porous fibrous layer and a second porous fibrous layer and an air permeable intermediate film layer situated between the first and second porous fibrous layers and wherein the adjacent surfaces within the three layer system are interconnected, wherein the second porous fibrous layer has an area weight AW2 that is varying over the surface and wherein at least for areas of the three layer system with a total thickness t between 5 and 35 mm, the area weight AW2 relates to the total thickness t of the three layer system as following 25*t+175<AW2<45*t+475 wherein t is in mm and AW2 is in g·m?2 and wherein the area weight AW2 of the second porous fibrous layer is increasing with increasing total thickness t of the three layer system.
