Abstract

The absorption material of the structure is held down by a supporting construction, this supporting construction being laminated with a sheet on its side facing away from the absorption material. The sound-damping structures according to the invention are suitable for the damping of sound waves in gas streams containing moist dust with an adhesive tendency. <IMAGE>
