12 Pack Self-Adhesive Acoustic Panels, 12" X 12" X 0.4" High-Density Sound Proof Foam Panels for Walls, Polyester Fiber Soundproof Wall Panels for Home & Office (Black)

I installed about seven of these acoustic panels on my Bambu P1S, and the difference was honestly incredible. The high‑pitched whine that used to leak out of my 3D‑printer closet is completely gone — I can’t hear the printer at all anymore, which makes me ridiculously happy. The panels were easy to work with, too. I cut them cleanly using just a ruler, a box cutter, and a cutting board, and they produced zero dust or debris. The adhesive backing feels strong and reliable, and the panels themselves look sleek and low‑profile once installed. Overall, I’m extremely satisfied

Excellent product, bought them for my daughter for she had a little barking dog. Used them on the back of her apartment door by doing a decorative diamond pattern and they helped to lower the volume iof his sound. Very easy to work with panels.

I can't recommend the panels more highly. The feel is rigid and they look very professional for the price. So much so, I wish I'd purchased two colors to make an alternating pattern - it would draw the eye to them even more. They're simple enough to setup that it's actually fairly fun. As long as the first panel is correctly oriented, just butt them together carefully and they align perfectly. Cutting them works well - just use a box cutter and a metal straight edge. Buy these.

These panels are perfect colors and the design. They stick on with ease and hold up well under any environment. I use these for the color, design and light weight for my office in an RV! Great product and does not look cheap. Easy peasy to install.

Ordered two packs to help mitigate the echo in my office with my 11’ ceilings. I used a utility knife to cut up the pieces, but I would recommend something sharper, as some of the edges look choppy. Not so noticeable with the white panels on a beige wall, but if I had picked the black they definitely wouldn’t look as clean. The adhesive on the back is suuuuper sticky. When I misplaced one panel and went to pull it up to move it, half of my paint (I moved into a new build and the paint was about 6 mo old) came up with it, and the panel was bent beyond repair. After applying a few stickers, I used a small loop of painter’s tape on the back of the rest of the pieces, since I wasn’t sure how the design would turn out and didn’t want to destroy my wall to find out. It’s held up for over a month so I may not even bother with the adhesive, but my co-workers said there’s no more feedback when I’m on video calls, so at least they work 🤷🏼‍♀️

They were great

To cancel noise you got to get into the drywall and get noise canceling panels. These easy to tape on the wall panel squares are simply to help yourself feel like less noise is occurring out from your space into another space. And maybe it reduces noise travel by a hair and a hair is still something like furniture, furniture in a room also helps to cut down on noise, as long as it doesn’t have a glass surface that can enhance echo effect. The panels do their job, they stay put on the wall as they are supposed to, but it seems this and things like this are really for us to feel more confident that less noise is leaving our space than whether these things actually are working the way we would really like them to. Is it worth buying...I don’t know...it depends if it will help you feel less stressed by having them not whether they work or not.

Placed these on the wall behind and beside my computer desk. They noticeably reduced the noise of multiple computer fans. I can hear music more clearly at a lower volume than before.

Didn't help with the room echo at all.
