Title Compact sound absorbers for low frequencies
Bibliographic information May-June 1992, Vol.38, No.3, p.109-117. Illus. 10 ref.
Abstract The design of a compact and efficient sound absorbing structure constructed without porous material is described. The structure was designed as a simple resonator comprising a panel perforated with small holes backed by an air space. Its performance was predicted by a theoretical model and verified experimentally using a new facility designed to measure acoustic properties of materials at low frequencies. Test results show good agreement between theory and experiment and confirm that the extension of the proposed theory to the low frequency range is possible.
