ABSTRACT:
It should be possible to manufacture, in a simple manner, a sound-absorbing wall-lining (3) consisting of a material to be applied to the wall which needs lining, and a resilient layer (4, 5) of foam, e.g. foam rubber, felt, or similar material, having locally distinctive sound-absorbing capacities, and whose thickness will possibly remain uniform, provided the resilient layer (4, 5) contains a filler with locally distinctive degrees of cross-linking--corresponding to distinctive sound-absorbing capacities.
