Abstract
A recent round robin on sound absorption measurements in which the same sample and measurement equipment were taken to a number of laboratories in Canada and the United States also provided an opportunity for sound power measurements to be made on the same source in a number of different reverberation rooms. Any differences in the measured levels should reflect the variations in the geometry, absorption, or diffuser configuration of the reverberation rooms.
