KERRAM Acoustic Wall Panels, 4-Pack 47 x 24-Inch Black Grooved Panels
Product description
At 47 x 24 inches per panel, the KERRAM set is designed to cover wall space with four large, black acoustic panels. Their vertical grooves give the surface more visual texture than a flat panel.
Each panel is made from high-density polyester fiber and has a self-adhesive backing. The listed use cases include recording studios, home theaters, offices, and living rooms.
The product is presented as sound-absorbing treatment for echoes and noise, not as a fully specified wall-isolation system. Installation is described for clean, flat surfaces.
Tech summary
- Format: 4-pack of acoustic wall panels
- Size: 47 x 24 inches per panel
- Material: High-density polyester fiber
- Color: Black
- Design: Intermittent vertical fluted grooves
- Installation: Self-adhesive backing for clean, flat surfaces
- NRC: 0.95 or higher, as stated in the product details
The grooved face is intended to help disperse and absorb echoes, while the black finish and vertical pattern also make the panels a visible part of the room. The listed NRC figure is a product claim, no test conditions or measurement details are provided. That distinction matters if you are comparing acoustic treatment with a solution intended to block sound traveling through a wall.
Everyday compatibility
KERRAM names recording studios, home theaters, offices, and living rooms as potential settings. In a home office, for example, the panels could be arranged on a clean, flat wall as part of an effort to reduce room reflections during calls or recording. The listing does not specify how much wall area the four panels cover when installed together, so placement will depend on your layout and the area you want to treat.
You’ll appreciate it if you want a wall-mounted treatment with a decorative grooved finish, rather than plain acoustic foam. The adhesive backing avoids the need for separate adhesive or tools according to the product details, but the stated installation surface is clean and flat. No guidance is given on removal or repositioning, so the set is best considered for a placement you have already planned.
Getting the most from it
Plan the panel arrangement before peeling off the backing, then apply the panels to the intended clean, flat surface. Their large stated size may suit a prominent wall area, while the four-piece format gives you several panels to position. The product details do not provide a mounting layout or coverage diagram, so measure your wall and decide where the grooves and black finish will work visually as well as acoustically.
If your main goal is to improve the sound inside a room, these panels are described for absorbing echoes and noise. If you need a specific reduction in sound passing between rooms, the listing does not provide enough information to establish that result. Not the best choice if you need documented sound-isolation performance or installation guidance for uneven surfaces.
Before you decide
What are the panels made from? They are listed as high-density polyester fiber, with a black grooved surface.
How are they installed? Each panel has self-adhesive backing. The stated method is to peel it off and stick the panel to a clean, flat surface.
Where does KERRAM suggest using them? The listed settings include recording studios, home theaters, offices, and living rooms.
Final verdict
This set makes sense for someone planning a decorative, adhesive-backed approach to treating echoes on a clean, flat wall. Its large 47 x 24-inch panels, four-piece format, and vertical grooves distinguish it from smaller, plain foam tiles. Choose it for the stated sound-absorption use and appearance, look for a more fully documented solution if your decision depends on verified sound blocking, installation on textured walls, or precise coverage information.
