TroyStudio Thick Acoustic Foam Panels, 12 X 12 X 2 Inch 36 Pcs Broadband Sound Absorbing Foam, Dense Soundproof Padding Tile, Recording Studio Foam Absorber, Groove Decorative 3D Wall Ceiling Panel

A must have for room treatment.
I got this cause my F36 towers are rear ported and I can only have the speakers a foot away from the wall. The air pressure from the port would hit the wall with enough force that it made the wall vibrate causing lots of resonance and making them sound boomy making the sound a bit muddied. And it was real bad in the rooms behind the wall like headache bad. Anyways I tried the egg shaped ones but didn’t do anything then I saw these and gave it a shot. Boy I’m glad I got them. I put them behind the port 4 for each speaker 4 for the subs and they eliminated the problem for the most part. On a scale of 1-10 I say it’s 9.0 I am very happy! It eliminated the resonance making my speakers sound better. When they arrived they were compressed in bags but once I opened one bag they just bursted out lol. You have to buy two sided tape or something equivalent to stick them to the walls. I highly recommend these well worth the money!

Purchased 20 Packs! Tested No VOC or Formaldehyde
1) Not Toxic! I have an Air quality meter and I set these next to it after opening. No bump in either VOC (Volatile Organic Compounds) or Formaldehyde (HCHO) levels! These do have a new mattress type smell mixed with the smell of pet food, but maybe they were stored a long time in a factory. It isn’t a very strong smell, even with 120 of them unpacked.2) They do decompress eventually! They took a lot of work to decompress! Leaving them out did not bring them to their full decompressed state. I had to lay flat under sanding water in my sink and get all the air out by pressing down against the bottom of the sink with my palms. Temp of the water didn’t effect them. I found I was able to do this 10 at a time which for me was helpful since I have 120 squares. I had to gently wring out each square after getting all the air bubbles out, since the water was soaked up into them like a sponge that wouldn’t let go. I left them out thinking they would dry (12 hours ish), but since these trap whatever they absorb for a long time I got impatient and had to put them in the dryer on very low for an hour. each load I did notice the pet food smell when taking them out of the dryer but it wasn’t harsh, seems natural ish, or at least inert. Very sensitive people may not like these due to the ‘perception of toxicity’ which on the scale of 1 to 10 would be around a 33) They Hang! Before writing this review I hung 6 on the wall – I didn’t use Adhesive, I used long thumb tacks which works for my needs. These are VERY light weight. Essentially, think air conditioner foam light. A part of me wonders if these were blocks of Air Conditioner Foam laser cut and then immediately compressed into plastic for shipping. But I’m not an expert so that’s just a theory.4) I can’t speak to sound proofing ability but I feel like these will only help with echo. If I notice a massive difference maybe I will edit my review, but my sound gear wont arrive for about 7.5 years probably (jk).5) OVER ALL – I LIKE them a LOT. If only just for the futuristic style look! They definitely give a perception of being able to improve my sound quality, so for my dates watching a movie with me that works fine. ;)Final thoughts: The value for money isn’t really there. If you can find this style in another product, I would opt for that. I probably wont buy these again unless this style doesn’t exist in another more dense product. The time wasted on decompression was money I could have spent elsewhere. Buuuut… the style tho! Ugh – just so cool! 🙂

Great… Mostly.
To start, I got two packs of these to line my game room.Most of the tiles are great and I ended up having quite a few extra to spare. The issue with these guys is that they vacuum seal twice.They to take shape easily if you let them sit for a few days, you don’t need to shove them in the bath.The issue came When I stated to dig through the tiles and pick ones to mount. They are not equal. I would say around 20 or so of the 72 (2 x 36 packs) I ordered were misshaped or have defects on the ends of them that ruins the look. That’s around 25% of the tiles!The price is also just a bit expensive for the amount of defects I got. The good tiles look great and adhere well to the wall. I did try to soak the defects, it did not work.If you plan to trim or cut this, it won’t matter, but since I put them up whole and wound up with a pile of “rejects” I can’t give this 5 stars.

Não é nada igual o que aparece na foto, não isola nada

I love these panels , so I’ve decided to treat the whole space. They do expand fine if unpacked and left over night. There is a bit of an odor that dissipates over a few days. I also like how they look on the wall after some 3M tape and some patience.
