TR 15 - Calculation of Sound Transmission Parameters for Wood-Framed Assemblies

65 pages (3.9 MB PDF) January 2019

The 2018 International Building Code provides two parameters to establish minimum acoustical requirements: Sound Transmission Class (STC) and Impact Insulation Class (IIC). Compliance with these requirements may be demonstrated either through testing or through engineering analysis based on empirical test data from other similar assemblies. The TR15 shows how to use the new AWC empirical model for compliance, which may be used for analysis of wood-frame floor-ceiling assemblies to estimate the code-regulated STC and IIC sound transmission parameters.
