The 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. This app provides a means of analyzing wood-framed floor-ceiling assemblies to establish STC and IIC values, based on the AWC test-based model described in TR15.
What's new in this version
- Provides an algorithm that automates the TR15 method for calculating sound transmission class (STC) and impact insulation class (IIC) for wood-framed floor-ceiling assemblies.
