Abstract
Abstract Results of an experimental performance qualification of a large reverberation room in the Noise and Vibration Control Laboratory at Owens-Corning Science & Technology Center, Granville, Ohio, are reported. The qualification testing was done according to ASTM C 423 – 90a and a proposed revision of ASTM C 423 being developed by Task Group E–33.01–D of ASTM Committee E–33 on Environmental Acoustics. The proposed revision puts requirements on spatial uncertainties in the reverberant field in addition to the uncertainty in the total number of decay rate measurements. Results of the performance qualification show that this room meets or exceeds requirements for a reverberation chamber for measurement of sound absorption and sound absorption coefficients in the 100 to 5000 Hz third-octave bands.
