No sound dampening

$0per sq ft

½” drywall screwed straight to the joists, open cavities above. Every footstep thumps straight down the wood and every voice carries through the air. Fine for storage; rough for a theater room or a bedroom under the kitchen.

Level 1 · Good Selected

Rockwool Safe’n’Sound

$2.75–3.75per sq ft

Dense mineral-wool batts friction-fit between the joists. Regular insulation feels like cotton candy; this feels like packing foam. That density soaks up the sound traveling through the air — voices, TV.

Insulation in every joist bay. Footsteps still come straight down the wood.
Level 2 · Better Selected

+ RC-1 resilient channel

+ $1.00–1.50per sq ft

Galvanized steel channel runs across the joists so the drywall never touches the wood. That ½” gap breaks the path footsteps take — down the joists, into your ceiling. This is the level that kills the thumps.

Floating drywall, ½” off the joists. Includes Level 1.
Your ceiling drops about ½”. Most people never notice.
Level 3 · Best Selected

+ 5/8″ drywall

+ $0.85–0.95per sq ft

Swap the ½” board for 5/8″. Thicker and denser, so it’s simply harder for sound to push through. Stacked with Rockwool and channel, this is as quiet as a basement ceiling gets.

Heavier ceiling board. Includes Levels 1 and 2.
