Our take on the Black 2 Inch Self-Adhesive High Density Acoustic Dampening Foam Panels, 36 Pack

A 36-pack of black 2-inch acoustic foam panels with self-adhesive backing, sold as a wall-mounted dampening set. The listing's own specs conflict: the title says 2 inches thick, but the spec sheet says 1 inch and 3 panels covering 100 sq ft, so confirm thickness and panel count before ordering. At $114.50 at Walmart as of November 4, 2026, it is the only new price on record, so there is no recent range to judge it against.

Pros
  • 36 panels cover a lot of wall for one purchase
  • Self-adhesive backing skips separate glue or spray
  • 2-inch profile absorbs more mid and low-mid sound than thin 1-inch tiles
  • Black finish blends into most rooms
Cons
  • Specs disagree on thickness (2 in title vs 1 in spec) and panel count (36 vs 3)
  • Only one new price listed, so no way to tell if $114.50 is a good deal
  • Adhesive-backed foam can peel paint or leave residue when removed
  • Foam panels do little for deep bass; they mainly tame flutter echo

Questions and answers

Is this 2 inches thick or 1 inch?
The title says 2 inches, but the spec sheet lists 1 inch. Ask the seller to confirm before you buy, since thickness changes how much sound the foam absorbs.
How many panels do I get?
The title says 36, but the specs list 3 panels covering 100 sq ft. That is a big difference, so verify the count with the store first.
Is $114.50 a good price?
Only one store lists a new price, $114.50 at Walmart as of November 4, 2026, so there is no recent range to compare. Check the price per square foot against other foam panel packs.
Will the adhesive damage my wall?
Self-adhesive foam often pulls paint or leaves sticky residue when removed. Test a small piece first, and use removable mounting tape on painted or wallpapered walls.
Will these panels soundproof my room?
No. Foam panels reduce echo and reflections inside the room. They do not block sound passing through walls, doors or floors.
Where is the Black 2 Inch Self-Adhesive High Density Acoustic Dampening Foam Panels, 36 Pack cheapest?
At Walmart, for $114.50, as of our latest check.
