Update on the current ASTM building acoustics inter-laboratory studies

Abstract

In the last few years, ASTM E33 committee on Building and Environmental Acoustics has undertaken a program to improve the precision and bias statements in its laboratory and field standards. This is done through analysis of inter-laboratory studies. At the time of writing, there are approximately 10 such inter-laboratory studies either currently in process or recently completed. This paper will give a brief overview of these activates. It will highlight those studies involving laboratory building acoustics standards, including standards on sound transmission loss, impact sound transmission, sound absorption in reverberation rooms, and sound attenuation between rooms sharing a common ceiling plenum.
