New report addresses sound transmission of wood-framed assemblies

AWC document provides empirical sound transmission model.


By Peter Fabris, Contirbuting Editor | November 7, 2018

The American Wood Council (AWC) released a new report on sound transmission, “Technical Report 15 (TR15), Calculation of Sound Transmission Parameters for Wood-Framed Assemblies.”

“Building codes stipulate minimum performance requirements regarding noise transmission through certain interior walls, partitions, and floor-ceiling assemblies,” according to AWC Vice President of Engineering Brad Douglas. “This initial version of TR15 summarizes how these code provisions apply to floor-ceiling assemblies and demonstrates how wood-framed floor-ceiling assemblies can comply with a calculation-based analysis approach.”

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 new report shows how to use the new AWC empirical model, and may be used for analysis of wood-frame floor-ceiling assemblies to determine compliance with STC and IIC sound transmission parameters.

Conflict resolution is a critical skill for contractors

Contractors interact with other companies seventeen times a day on average, and nearly half of those interactions (eight) involve conflicts, according to a report by Dodge Construction Network and Dusty Robotics. The study suggests that specialty trade contractors, in particular, rarely experience good resolution from conflicts.

California bill would limit where distribution centers can be built

A bill that passed the California legislature would limit where distribution centers can be located and impose other rules aimed at reducing air pollution and traffic. Assembly Bill 98 would tighten building standards for new warehouses and ban heavy diesel truck traffic next to sensitive sites including homes, schools, parks and nursing homes.
