摘要:
Reverberation chamber measurements are presented for resonant absorber constructions covering a range of resonant frequencies. Types of constructions tested were (1) thick layers of porous material covered by the facing and backed by a hard wall and (2) facings covered with a resistive cloth layer and mounted with air space backing. Measurements were made with thicknesses up to1412 in.behind the panel to secure high absorption at low frequencies.
