12 Pack 2"X12"X12" Sound Proof Foam Panels for Walls, High-Density(35kg/m3) Soundproof Wall Panels with Upgraded Multi Groove Design, Quick Recovery Acoustic Panels, Wall Panels, Black

This foam has a more irregular surface, so that's better for diffusing sound reflections, which is the whole point of these things; they're not going to "soundproof" anything, but they will cut down on boxy reflections in a room sound. The foam itself has a bouncy, springy feel to it, and there are lots of iridescent particles in the foam that catch the light, but aren't totally garish. And while this can't possibly be an attribute that was intended, I have found that it's possible and helpful to be able to wedge a wire or cable in between the panels if you need to hold it up.

Took me a while to get these up and in use, but they've served me well so far. I had to hunt around a bit for suitable adhesive to get them to stick to the wall, but they've stayed up so far, and they appear to be doing their job as far as sound absorption goes. I'm not recording music, just spoken audio, so I don't know how they would perform at louder levels, but they've been good for me and my personal projects.

Fairly simple sound panels. I got these to set up in my room to help cancel out some echoing while I am gaming. They stuck well for me and have seemed to help reduce the echoing of the small room while I talk. Not too much to say simple and easy to use!

Feels kind of cheap but it gets the job done.

At best, you will get some absorption in the highest frequencies. It is too thin and, even though foam isn't as effective as proper treatments, this isn't even the right kind of foam. It is soft and pretty, but compare it with something like Auralex and you will feel the difference.

My bedroom has the thinnest walls in my entire house. There is only a single layer of insulation in the room, as opposed to most of the house which has thicker walls. Don't know why, but that is the case.Because of that, my bedroom is not always that quiet. Especially when my neighbors decide to start partying at 10pm. And of course, they don't care that they are bothering me or some of the older neighbors. So, what am I to do?Soundproof the walls. Thankfully since it is the second floor, and the ceiling is slanted due to the roof, there's only a small amount of wall that actually needs to be soundproofed. It's not a perfect solution, and its not the most pleasing to the eye, but, I need my sleep. My wife needs her sleep.These work pretty well. The sound that comes through is much less now that they are up.These come vacuum sealed, so when you first open the package, give it some time for them to come back to life, so to speak. I gave it about 24 hours before I put them up, to make sure they were all properly sized and everything. Probably could have done it sooner, but, I am used to the 24 hour thing for things sealed in this nature.No adhesive came with these, so you need to use your own double sided tape.

Works exactly as intended. Using this to build an at home studios and so far I am not disappointed! Would recommend to those in need of decent soundproofing

Got these to make a little voice recording booth. The quietest room in my house is the finished attic (hard walls and ceiling, carpeted floor) and so I used these foam tiles to dampen one corner where I put a mic.Like all foam of this type, they stink like awful petroleum waste when first opened, but I left them alone to air out for a few days (maybe 3?) and by the time I came back they were ok. The adhesive didn't work on my super duper old wood paneling walls or the popcorn texture ceiling (can you guess what decade my attic was finished in?!) but a few staplegun staples in each did the job.It didn't make the corner of the room dead silent, but it did enough to defeat echoes that recordings made with the mic in that corner sounded tremendously better than prior to adding the foam.The funky shape actually helps - the more surface area there is, the more sound gets absorbed. all those edges and facets help the tiles absorb more vibrations.
