Sound transmission in mass timber floor-ceiling assemblies
Abstract
As mass timber structures become more commonly used in the United States, laboratory acoustical data is needed to guide the design of these buildings. In the fall of 2019, a laboratory test program of airborne isolation per ASTM E90 and impact isolation per ASTM E492 of mass timber floor-ceiling assemblies was undertaken. Cross Laminated Timber (CLT), Dowel Laminated Timber (DLT) and Mass Plywood Panel (MPP) panel types were tested with ceiling conditions selected based on 2021 IBC fire code requirements. Comparisons will be made between panel types and other contemporary building types using broadband, low, and high frequency metrics.
