ACOUSTIC PROTECTION SYSTEM FOR A MOTOR VEHICLE

The invention relates to an acoustic protection system (1) for a motor vehicle, comprising: two walls (2, 3) extending opposite each other; an elastically compressible acoustic decoupling layer (4) arranged compressed between the two walls at least along the periphery thereof, the layer having two opposite faces (5, 6) pressed against each of the two walls, the two faces being connected to each other by an edge (7), the layer being housed in a closed pocket (8) made of plastic film so as to form a sealing barrier on the edge, at least one air passage hole (9) is provided in the bag opposite the at least one surface, the hole being provided at a distance (10) from the edge, so that a seal (11) produced by the bag bearing against the respective wall is provided around the hole. 本发明涉及一种用于机动车辆的声学保护系统(1)，该系统包括：彼此相对延伸的两个壁(2，3)；可弹性压缩的声学解耦层(4)，其至少沿其外围压缩布置在所述两个壁之间，该层具有分别压靠所述两个壁的每个壁的相对的两个面(5，6)，这两个面通过边缘(7)彼此连接，该层被装在由塑料膜制成的封闭的袋(8)中，从而在边缘上形成密封屏障，至少一个空气通道孔(9)对着至少一个面地设置在袋中，该孔设置在离边缘一定距离(10)处，以便在孔周围设置由袋承靠在相应的壁上产生的密封件(11)。
