Our take on the Self-Adhesive Acoustic Dampers Sound Proof Foam Panels, 18 Pack 0.4 in, Black

A set of 18 self-adhesive acoustic foam panels in black, sold as a quick peel-and-stick way to cut echo and flutter in a room. The listing describes 0.4 in thickness, while the spec block says 1 in and 100 sq ft across 3 panels, so confirm the actual thickness and panel count before ordering. At $105.42 at Walmart as of November 4, 2026, it is the only new price on record, so there is no recent range to compare against.

Questions and answers

Is 0.4 in foam thick enough to reduce echo?
It will soften claps, voices and other high-frequency reflections. It will not stop sound passing through walls or tame low bass; that needs thicker panels or bass traps.
How much wall does 18 panels cover?
The listing gives 100 sq ft, but that figure is tied to a 3-panel spec that does not match an 18-pack. Measure one panel when it arrives and plan coverage from that.
Will the adhesive damage paint?
Peel-and-stick foam usually lifts loose paint or leaves residue on drywall. Clean and degrease the wall first, and test one panel in a corner before covering a whole wall.
Can I cut the panels to fit?
Yes. A sharp utility knife or long scissors cuts the foam cleanly, and the adhesive backing can be trimmed to match.
Is this cheaper than acoustic panels from brands like Auralex?
At $105.42 at Walmart as of November 4, 2026, it is priced like budget foam. Branded studio foam costs more but usually states its fire rating and density.
Does it come with mounting hardware?
No. The panels rely on their own adhesive backing, so no screws, clips or spray adhesive are included.
Where is the Self-Adhesive Acoustic Dampers Sound Proof Foam Panels, 18 Pack 0.4 in, Black cheapest?
At Walmart, for $105.42, as of our latest check.
