How we ranked these acoustic panels
Every pick ranks in Amazon's best-seller list for its category and has a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.
- NRC rating weight 2
- Thickness weight 1
- Fire-rated weight 1

Buying advice: acoustic foam for walls
Match thickness and pack size to the wall
Thickness and pack size decide how much wall you cover and how the foam sits. The Knightsacoustic panels are 1 inch thick, the Dmsky and BangXyth panels are 2 inches thick, and the varrisin panels are 48 by 24 by 2 inches. Pack sizes run from 4 panels in the varrisin pack to 52 panels in the TDHLYJHF pack, with 48 in the Knightsacoustic pack, 50 in the Dmsky pack and 12 in the BangXyth pack. Measure the wall, then count how many panels the area needs.
Check how the panels attach to the wall
Attachment decides whether the panels stay up and whether they come off cleanly. The Knightsacoustic and BangXyth panels are self-adhesive, so they stick straight to the wall with no extra glue. The Dmsky panels need spray adhesive or nail-free adhesive, which is not included, while the varrisin panels come with adhesive stickers. If the wall is rented, check the adhesive type before you stick panels to it.
Let new foam air out and recover its shape
Foam arrives pressed flat in the pack and needs time to reach its full shape. Air the Knightsacoustic panels for 24 hours after opening, and give them a matter of hours to recover their shape after ventilation. The Dmsky panels need about 24 hours in a ventilated place, or a soak in water for a few minutes and drying in the air. The BangXyth panels expand and return to shape within seconds after unpacking. Give the panels that time before you judge the fit on the wall.
