SOUND PROTECTION PANEL FOR CLADDING A WALL OF AN AUTOMOTIVE VEHICLE

The invention relates to a sound protection panel (1) for cladding a wall of an automotive vehicle, said panel including, in particular so as to form a mass-spring system: a lower spring layer (2) based on a resiliently compressible material; an upper mass layer (3) based on resiliently compressible...

Zusammenfassung:	The invention relates to a sound protection panel (1) for cladding a wall of an automotive vehicle, said panel including, in particular so as to form a mass-spring system: a lower spring layer (2) based on a resiliently compressible material; an upper mass layer (3) based on resiliently compressible foam flakes (4), said flakes being bound together by a two-component fibre-based bonding agent (5) comprising a core (6), said core being fusible at a high temperature or infusible, and a sheath (7) fusible at a lower temperature, said flakes being fused with said sheath so as to form an upper agglomerated layer (3).
