| Figure 34 and 35 show only two of the many
sound-resistant floor and wall assemblies that can be obtained with wood structural
panels. Some floor-ceiling assemblies also qualify as fire-rated construction. While many listed assemblies were tested using plywood, other APA OSB and
composite structural-use panels may be substituted on a thickness for thickness basis.
Because of their similar strength and stiffness properties and slightly higher density,
use of these products in lieu of plywood will not compromise the STC or IIC ratings
of the tested systems.

Noise-Rated System, Form W460.
