Room Sound Field Diffusion Effects on Measuring the Sound Absorption Coefficient

Tang Wei-hong

Abstract

To measure the sound absorption coefficient in the reverberation room,theoretically it needs the room sound field spreading evenly,but in fact it′s not.It′s one of the main causes to use the method of reverberation room to measure the sound absorption coefficient mistakenly.The effect of unevenly sound field to measure the sound absorption coefficient is analyzed,and the necessity to take effective spreading measure in reverberation room is explained.
