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
