They contain cylindrical air cavities able to oscillate, the bigger ones of which are sound absorbing resonators. The number of cavities per unit area can be adapted to the thickness of the steel plate in order to attain the highest possible absorption in the desired frequency range.Reflexion factors below 10%, i.e. absorption factors higher than 99%, have been obtained in the frequency range 9 to 18 kc/s. The design of the absorbers and the physical principles underlying the problem are described in detail. Some aspects of the measuring technique and the technology of rubber are mentioned.", }
