Acoustic Sleeper Pads are 1/4-inch thick neoprene, 1-1/2-inches square. They are easily and quickly stapled to the underside of span-rated plywood. The Acoustic Sleeper has been issued US Patent No. 10,041,245.
Pads are generally used in the field of panels and along tongue-and-groove edges at a spacing determined by panel span rating to limit deflection. Pads may be used along terminal edges and at butt edges of panels at a closer spacing; strips are recommend at these locations to eliminate any deflection.
