A summary and discussion of impact and airborne sound isolation data collected in mass timber buildings in the Pacific Northwest
Abstract
This session will present the results of airborne and impact testing on mass timber building assemblies performed by the University of Oregon’s Institute for Health in the Built Environment (IHBE). Over the past 7 years, IHBE has collaborated with architects, engineers, and contractors to better understand the implications of design and construction decisions on the acoustic performance of mass timber buildings. This has resulted in IHBE conducting acoustical testing on eight constructed mass timber building assemblies in Oregon. These data will be used to identify and explore trends and design opportunities. This presentation is part of a collaborative effort between the IHBE, University of Oregon’s Oregon Acoustic Research Laboratory (OARL), and IHBE industry consortium affiliate, Liniar Studio, an acoustic design firm located in Portland, OR. A primary goal is to leverage Oregon’s high concentration of mass timber buildings to collect and analyze acoustic isolation data with the goal of identifying design opportunities to increase acoustic comfort, tenant satisfaction, and overall health and safety in buildings.
