Title: ACOUSTIC PANEL FOR LINING A WALL OF A MOTOR VEHICLE
Abstract:
The invention relates to an acoustic panel (1) for lining a wall of a motor vehicle, said panel comprising, in particular in such a way as to form a spring-mass system: a lower spring layer (2) comprising elastically compressible material; and an upper mass layer (3), at least one of said layers, known as the bonded layer, including flakes (4) of elastically compressible foam, said layer being equipped with a flake-binding agent, said agent comprising dual-component fibres (5) having a core (6) that is fusible at a high temperature or infusible and a sheath (7) that is fusible at a lower temperature, said flakes being bonded by means of the fusing of the sheath.
