DEKIRU Sound Proof Foam Panels 18PACK, Acoustic Panels Self-Adhesive, Square 45° Edge designed Sound Proof Panels For Walls, Wall Panels For Interior Wall Decor, Home Studio and Office (Dark Grey ）

These are some of the only pre-built acoustic panels I have found that actually do a great job of reducing sound reflection. I'd recommend picking up three 18 packs worth of tiles to effectively make five-tile tall groups positioned around your room. They're great! Completely finished my setup thanks to these.Most acoustic *foam* does not work. Literally, just does not work.I'm talking about sound treatment, not sound "proofing" here. If you are looking to *sound-proof* ANYTHING, do NOT buy acoustic panels or foam at all. The only thing that will sound-proof anything is solid matter, like concrete or wood.Sound treating on the other hand, involves reducing the reflection of sound off of the surfaces in a space. Acoustic foam you'd normally get (that wedge-shaped stuff you see in youtuber backdrops that looks really cool) is simply not dense enough to effectively absorb enough sound to prevent a reflection.

One of the rooms of my house has a radon fan on the wall outside, and it causes a 24/7 low vibrating hum which is kind of annoying and is audible throughout the room. I had my doubts these acoustic panels would help, so I bought just two packs and put them on the wall. It's only halfway done and already I can tell there's a huge difference!!! The room is now like 3X as usable as before! It's not completely soundproofed, but the noise is dampened enough that it's not very noticeable. I ordered two more packs to finish the wall! I'm super happy with these. They also look nice on the wall.

Honestly after searching a ton of acoustic panels I settled on this because everything pointed towards these being effective. I am not impressed. I purchased 5 boxes and my wall is covered but the sound was barely muffled. My problem still exists - noisy neighbors. 🤷🏽‍♀️

I ordered the pack of 18, and only received 12. Easy to set up, but I bought more than it came with.

Reduced some of the noise inside out thou not some much coming in from the hallway

I put these around my window box to buffer noise from the street below. Despite the surfaces being less than ideal, these adhere perfectly and I was also able to cut them to fit with heavy sheers, with no problem. These work very well, and are well priced compared to other options I've seen.

I used these to create a sound dampening cover for my blender. I took a box and covered the inside and out with these panels; the adhesive held very well, and I had no issues building my cover. The purple is a cute color. They obviously don't completely sound-proof the blender, but they do a great job at dampening the noise and making it more tolerable.

Purchased a pack of 18 and only got 17!

Compre dos paquetes y me alcanzó para diseñar la cabecera de mi cama queen (solo envío un par de fotos, porque no tendí la cama jejej). Buen producto, fácil de cortar y pegar.
