Abstract

In wood-frame buildings, structural shear resistance in load-bearing walls is sometimes provided using OSB or plywood sheathing board directly applied on the wood framing.  When these panels are used on both internal faces of a double-stud demising assembly with a drywall layer on each finished side, the sound transmission performance is significantly compromised by the air cavity resonance between the panels.  This was the subject of a 2015 Acoustics Week presentation.  As a follow-up, the mitigating effects of using a resilient mounting for the drywall are investigated from recent field measurements.
