Best Option: Decouple the Ceilings
Ceilings are more difficult to isolate than walls because of the significant mass and lack of resilience. These characteristics limit the types of products that can be used to isolate airborne and footfall impact noise in ceilings. Expect two to three times the isolation with resilient clips in ceilings over the next best option, a damping compound or pre-damped drywall.
Combine decoupling with damping for maximum isolation of airborne and footfall impact noise.
Second Option: Dampen the Ceilings
Damping standard ceilings is not nearly as effective as it is for walls because a standard ceiling lacks resilience. Most gains from damping a standard ceiling will be the airborne noise transfer to the space above with very minimal gains in footfall impact noise isolation.
Damping decoupled ceilings is effective because the clip system or resilient channel will make the ceiling resilient.
Third Option: Add Mass to the Ceilings
Ceilings structures typically have significant weight and many layers of material so a small addition of mass will have minimal benefit. If you prefer to use MLV in a ceiling, then we strongly recommend installing 2 LB MLV instead of 1 LB MLV so that the product provides a more significant addition in mass and thickness to the assembly.
Low frequencies and impact footfall noise will not be isolated with MLV.
