The measurements are described of the absorption of sound by light porous compressible rubber wall-covering layers. The greater part of these measurements was performed according to the interferencemethod with normally incident sound. The method and the arrangement used are described. We investigate

In this second part the properties are described of homogeneous light sponge-rubber layers, coated with a very light non-porous surface-layer. In general, the results agree satisfactorily with theory. Low specific weight as well as a rather free mobility of the air (proper air-resistance of the inte

Sound absorbing materials with a non-porous surface-layer possess great advantages over the usuall well-known porous materials. These advantages are related mostly to their hygienic and decorative qualities. This kind of material, therefore, is already used in practice, the physical basis of the ab

The process of absorption of particles by the surface of a bubble in a melt is considered. The particles are also in the melt. Besides the particles, the melt also contains a surfactant which is adsorbed on the particles and on the surface of the bubble. There occurs an interaction which causes the
