The complex (1) has a flexible porous absorption layer (2), a sealing film (3), and a flexible elastic layer (4) that are arranged on each other to form a mass/spring type insulation system having absorption properties. The porous absorption layer has a porous matrix (5) with in which solid material particles (6) made of ethylene-propylene-diene-monomer are dispersed, where the density of the particles is higher than the density of the porous matrix. The porous layer forms a resistance to passage of air, and the matrix is made of agglomerated flexible foam flakes. |
