This Report presents the results from substantial experimental studies of sound transmission, together with an explanation of calculation procedures to predict the sound transmission between adjacent spaces in a building with wood-framed walls and floors. This Report presents two types of experimental data for wood-framed constructions:
- Test data for direct sound transmission through typical wood-framed wall assemblies and wood-framed floor assemblies, plus a summary of trends for such constructions and references to compilations of additional data
- Test data for flanking sound transmission measured following the procedures of ISO 10848 for coupled wall/floor junctions and wall/wall junctions
Worked examples for calculating the apparent sound transmission class (ASTC) rating between adjacent dwelling units are presented to illustrate how the experimental data can be applied.
