Multi-story schools will require close attention to sound transmission through floor-ceiling assemblies. Incorporate similar acoustical design strategies as with walls, increase mass and insulation, allow for air gaps to break vibration travel, and seal any penetrations.
When designing noisy spaces such as a music room, you may need to control sound transmission with breaks, so that the noise cannot travel through floors and walls. Breaks typically include double-stud walls, staggering the studs, or installing resilient channels or neoprene isolators to provide an air gap between the stud and drywall.
It is important to control sound transmission through joints and penetrations from duct work, plumbing, electrical wiring, and other openings made in the walls, ceiling or floors. It is best to seal these penetrations with a non-hardening acoustic sealant. These
Running calculations for credit compliance is the safest strategy to take. Relying on measurements taken after construction can be risky, in case you fall short and need to make costly changes.
