TroyStudio Thick Acoustic Foam Panels, 12 X 12 X 3 Inch 12 Pcs Broadband Sound Absorbing Foam, Dense Soundproof Padding Tile, Recording Studio Foam Absorber, Groove Decorative 3D Wall Ceiling Panel

Seems to work as advertised. Delivered in vacuum bag, but all panels expand within hours, with no problem or odor. They did deaden the sound for my application which was a "soundproof" box for a noisy device.

My only issue with these is that they really are hard to stick onto any adhesive that is not heavy duty/ permanent. I am opting for hooks to keep them up so I don’t damage my walls.

Man this treatment treats reflections so good, you’re gonna say Whoa! Hey! Why you treat reflections so good?!

I had to use tacks to hold up. there was NO adhesive at all yet the review asked me to rate the adhesive... Guessing it is missing?

The panels never reanimated after being removed from the packaging. They all still look squished. Made my recording space look like garbage. They make okay packaging material though.

I use this for my voice mask and ot definitely lowers the sound of hearing me while speaking

cheap, portable solution...use pin nail to mount them and you can move them very easily.

When it comes to acoustic panels, thicker is better, so these 3" thick panels will likely perform slightly better then the 1-2" panels that are typical at this price point. Having worked with these for a while now, I can confirm that this is the case - they provide slightly better sound dampening against echo/reflection. Whenever I review acoustic panels I always add in a public service announcement - these will not soundproof a room. Period. They are not designed for that purpose. They can be used as *part* of a soundproofing solution but won't get the job done on their own. That's because these panels are chiefly designed to combat high- to mid-range sounds as they bounce off hard surfaces (like walls and ceilings). That said, these panels do fairly well at the job for which they are designed and I do recommend them for that purpose. The design of them looks pretty cool on the wall - especially when grouped together. They are3 easy to install and are cut consistently creating a seamless covering is not overly difficult.

These tiles claim to be for soundproofing. I didn't expect it to completely soundproof my laundry room, but I did expect it to make at least a difference, especially at the price they charge. The fact that their is no adhesive backing is also just cheap. Like I said, if you're just looking to stop echos in a studio, these may work perfectly for you, but as a soundproofing product (which they themselves claim to be) it's a massive waste of money
