Yes, there are a few ways you can soundproof an existing ceiling without removing the drywall, with RSIC-1 Retro Clips being the overwhelming favorite. With that said, if acoustical performance is a top priority, our recommended approach is going to involve removing the existing ceiling so you can maximize performance.
Does soundproofing a ceiling really work?
Yes, soundproofing the ceiling – especially during new construction – is invaluable in multi-families like condos and apartments. Without it, every footstep and every voice will travel between floors, driving you and potential tenants crazy. By reducing the amount of impact noise and airborne noise traveling between spaces with a shared floor-ceiling assembly, you can reduce turnover rates, improve renter and owner satisfaction, and create a space that can truly be boasted as a luxury.
What's the best way to soundproof a ceiling?
The most effective method is by isolating the ceiling drywall from the joists with sound isolation clips. Quality ceiling soundproofing is achieved in commercial spaces like airports and hotels with the use of isolation hangers to hang the ceiling. And insulation in the cavity is part of a good soundproofing assembly.
Will adding insulation to my ceiling stop noise?
Yes, when dealing with airborne noise (like voices or TV), insulation is a part of any good soundproof assembly. Fiberglass insulation will typically boost an assembly’s STC rating by about 2–3 points, and soundproof options like denim insulation can add roughly 2 more points on top of that. When dealing with impact noise (like footsteps), insulation won't help the ceiling soundproofing.
Do acoustic panels help soundproof ceilings?
No, acoustic panels and foam are designed to absorb sound and control reverberation within a space, but they do not block sound. Most floor-ceiling noise is related to impact noise, which is structure-borne noise. However, it's worth noting that acoustic materials in the sound source side of an assembly can help to modestly reduce the amount of airborne sound by way of reducing echo and reverb. That said, this is one of the biggest misconceptions in our line of expertise, so we recommend reaching out to us to talk it through.
