Abstract

Measurements of sound absorption coefficients for 2 specimens in 4 similarly equipped reverberation rooms ranging in volume from 16 to 250 m3 show significant differences at low frequencies. There is an approximately linear relation between the measured coefficient and the logarithm of the room volume. This could explain some of the differences in measured coefficients between laboratories
