Abstract
The invention relates to a sound protection panel for cladding a wall of an automotive vehicle, the panel includes a mass-spring system. The panel has a lower spring layer based on a resiliently compressible material, an upper mass layer based on resiliently compressible foam flakes, the flakes being bound together by a two-component fibre-based bonding agent comprising a core. The core is fusible at a high temperature or infusible, and a sheath fusible at a lower temperature, the flakes being fused with the sheath to form an upper agglomerated layer.
