Quiet matters more than it used to. Remote work has made home offices a permanent feature of many Jonesboro AR homes, and shared bedroom walls in older houses and apartments often fall well short of modern noise expectations. This article walks through what actually works for soundproofing a room with drywall — and what does not, despite what the internet tells you.
Understand STC ratings
Sound Transmission Class (STC) is the standard measurement for how much sound a wall blocks. A standard 1/2-inch drywall wall with batt insulation comes in around STC 38–40 — good enough that you cannot hear normal speech, but loud conversation, music, and TV come through clearly. Quiet residential standards target STC 50+, which means normal speech is inaudible and even loud sounds are muffled.
What does not work: foam panels
Foam panels stuck to the wall do not block sound transmission. They reduce echo within a room, which is useful for recording studios and conference calls, but they do nothing for noise coming through the wall from the next room. Save your money for the actual wall assembly.
What does not work much: extra insulation alone
Adding more batt insulation to an existing wall cavity helps marginally, maybe 2–4 STC points. It is rarely worth the cost of opening up a finished wall just to add insulation. If the wall is already open for other reasons, go ahead — but plan for additional measures.
What works: mass + decoupling + damping
Real soundproofing uses three principles together: mass (heavier walls block more sound), decoupling (mechanically separating the two sides of the wall so vibration cannot transfer directly), and damping (energy-absorbing layers that convert sound vibration to heat). The most cost-effective residential assembly combines all three.
Recommended assembly: double drywall with Green Glue
Our standard residential soundproofing assembly: existing wall (or new 1/2-inch drywall), full coverage of Green Glue noise-dampening compound, second layer of 5/8-inch drywall, sealed perimeters with acoustic caulk. This typically delivers STC 52–55 on a wood-framed wall. It is the best dollar-per-STC-point upgrade available short of rebuilding the wall entirely.
Premium assembly: resilient channel plus QuietRock
For dedicated home theaters and music rooms we recommend resilient channel screwed to the existing studs, followed by QuietRock or equivalent sound-dampening drywall. This decouples the new wall surface from the framing entirely and can deliver STC 60+. The trade-off is cost — easily double the standard assembly — and the loss of about 1 inch of room dimension.
Do not forget doors and outlets
A great wall assembly is undone by a hollow-core door, an unsealed outlet, or an open HVAC return. Replace hollow-core doors with solid-core, seal door perimeters with acoustic weatherstripping, use back-boxes for outlets with acoustic putty pads, and consider acoustic boots on HVAC returns. These are small expenses that protect the investment in the wall assembly.
Ceiling soundproofing
Footfall noise from the floor above a bedroom is one of the most common complaints in two-story Jonesboro homes. The cost-effective fix is similar — add a layer of Green Glue and a second layer of 5/8-inch drywall to the existing ceiling. Resilient channel is even more effective if the ceiling is being rebuilt anyway.
Cost expectations
A typical 10x12 bedroom soundproofed with the standard Green Glue assembly runs $2,000–$4,000 in Jonesboro depending on whether existing drywall stays or comes off. A premium home theater assembly can run $5,000–$10,000 for a typical room. Both deliver substantial, immediately noticeable improvements in quiet.
