Abstract
Previous cross-correlative statistical research studies, combined with the results from past laboratory sound transmission loss round robin testing, illustrate that the laboratory-to-laboratory reproducibility of sound transmission loss testing is inordinately and unacceptably low. Industry building construction professionals use the results of laboratory sound transmission loss testing to determine acoustics-related building code compliance. As such, a forensic analysis of laboratory sound transmission loss is needed to narrow potential causes of cross-laboratory variability to a few primary sources. As a first step in this process, sound transmission loss measurements for two different assemblies are compared between multiple laboratories, each with their own different technicians and installation crews. Two different assemblies are then compared between multiple laboratory facilities with the same measurement and installation crew. The use of the same measurement crew at two different facilities resulted in much better statistical reproducibility than all previous reproducibility studies.
