Knightsacoustic Acoustic Foam Panels, 120-Pack, 1 x 12 x 12 Inches

Each charcoal foam panel measures 1 x 12 x 12 inches, and this 120-pack gives you multiple pieces to arrange across a room’s walls. The high-density acoustic foam is designed to absorb sound for acoustic treatment, helping manage room sound in spaces used for recording or listening.

These panels absorb sound rather than block it, so they’re intended for improving room acoustics—not as a substitute for a barrier designed to stop sound from passing between rooms. Adhesive is not included, so plan for a separate mounting method.

At a glance

The square format makes it straightforward to plan a wall layout using individual panels. Place them where acoustic treatment is needed, whether you’re organizing a recording area or addressing sound in another indoor space. Their foam construction and sound-absorbing purpose make them a practical alternative to approaches focused on blocking sound transmission: choose these when absorbing sound in the room is the goal.

The listing describes the panels as high density and identifies charcoal as the color. Since the pack contains 120 panels, you can plan coverage across a larger area or arrange them in selected sections. The final layout depends on the wall area you want to treat and how you choose to position the panels.

Getting the most from it

Think of the panels as part of a room’s acoustic setup. For example, in a recording space, you can arrange them on wall sections to add sound-absorbing material around the area where you record. In a listening or media room, they can serve a similar acoustic-treatment role. The manufacturer describes their function as absorbing sound rather than blocking it, which helps clarify the difference between treating room acoustics and soundproofing a space.

Buyers often mention easy installation and appreciate the panels’ insulating properties, while feedback on sound isolation and overall quality is mixed. Some also question the thickness or report panels coming loose after mounting. Because adhesive is not included, the choice of mounting method is part of planning the installation.

How to use it

Decide which wall sections you want to treat, then arrange the 1 x 12 x 12-inch panels across those areas. Use a layout that suits the space and the purpose of the acoustic treatment, rather than assuming the panels will block noise traveling through walls. For a recording setup, that means considering the room where sound is being produced and where you want the foam positioned.

Select a mounting method appropriate for your wall surface, the package does not include adhesive. With the panel count and dimensions in mind, you can map out the arrangement before installation and adjust the layout to fit the area. This makes the pack useful for planned wall treatment, whether you want a more focused arrangement or coverage across multiple sections.

Final verdict

For anyone setting up acoustic treatment with foam panels, this Knightsacoustic pack offers 120 charcoal squares in a consistent 1 x 12 x 12-inch format. Its sound-absorbing design suits recording and listening spaces where the priority is treating room acoustics. Choose it for that focused application, and plan the panel layout and mounting method around the walls you intend to treat.
