  • Housing lining
    Patent number: 5410111
    Abstract: A housing lining is disclosed with a self-supporting and airborne sound-absorbing layer of fibers. The fibers are compressed and glued together at least in the region of the edge surrounding the layer on the outside, to form an essentially pore-free supporting frame. The supporting frame may be provided with a cup-shaped bulge which comprises sound absorption surfaces which have a sound impedance of 20 to 200 Rayl.
