An in-depth look at empirical estimates of assembly performance

Acousticians often look for acoustical test data for wall and floor/ceiling assemblies that match the assemblies on their projects. However, with the endless possible permutations of assemblies, it can be difficult to find testing for an assembly that is an exact match. As a consultant, I frequently created engineering evaluations that documented my predicted performance of an assembly. As a manufacturer, I now have a say in what assemblies are tested, but I still can’t test all the possible permutations. This presentation is an overview of my current approach to assembly estimates, including the development of test series that are specifically intended to produce the data necessary to create good estimates.
