Lining for a housing, comprising a self-supporting layer (1) of fibres (2), which attenuates airborne sound. The fibres (2) are compressed and bonded, at least in the region of the edge (3) enclosing the layer (1) on the outer side, to form an essentially pore-free support frame (4), the layer (1) being provided at at least one first location with a bowl-shaped forward curvature (5), which is bounded by absorption areas (6) which have a flow resistance of 20 to 200 Rayl. <IMAGE>
