Sonic Acoustics 12 Pack 12 X 12 X 0.4 Inches Acoustic Absorption Panel, 3D Unique Soundproofing Insulation, Used in Home & Offices

Great addition to a small home office space… attractive and easy to install! The design gives a nice dimension to the wall space while the thickness gives you the noise reduction!

Ignore the reviews of folks saying they arrived flat; they're compressed, vacuum sealed for easy shipping .. of course they arrived flat! I bought these a year prior and just got to opening them up for use. Bought a 12pk of pyramid pattern and it arrived in a single vacuum sealed package. The inner pack had two vacuum sealed packs containing 6 compressed panels. I tried both methods to revive the foam and both worked, with some notes... If you've never worked with foam before, MOST foam products ship to you flat packed like these did. The leave out and let them rise method works best in a room that remains warm (between 65-75°F) with air flow. Sometimes the panels need more than 48 hours to fluff up, especially if they've been packed for awhile. Of the two methods, the soak and dry method worked best and fastest! A few tips: 1. USE HOT WATER. Get the water as hot as you can safely handle and soak the panels one at a time in a sink. Don't drop and flood them... hold them up and soak them under the faucet. If you have a hose you can use, even better. Soak the whole panel. If any edges still look thin or dry, use your fingernails and scratch the edge of the panel. As you scratch it you'll release the pressed edges. I promise they're not sealed or cut wrong. It may take a little effort, but they're fine. Make sure to really wringe them out before throwing them in the dryer. Use MEDIUM HEAT in the dryer for 20 minutes. If they're still damp, throw them in again for 10 minutes. Of the 12 panels, all 12 fluffed up fully however I did take the air fluffed panels and soak/dry them for fullness. These worked GREAT! Sound dampening in a recording corner for half the price!

Usually, you get what you pay for, so I figured these would be pretty decent at 3 and a half bucks a pop. Well they aren't. The pictures show a pure white smooth finish product, which these are not. They are more of an off white and some sort of fiberglass looking matting. They are also advertised as 12" by 12" and they're not. They're small. One of the panels came with a stain as well. If you're looking for white acoustic panels for a game room with led lighting DO NOT BUY THESE! The material absorbs the light.

Quality, low-cost option for acoustic foam tiles. Aesthetically pleasing and definitely dampens to a noticeable degree. I used ~34 tiles in a 9x10-ish square-ish room and it significantly affected the obnoxious amount of echo and reverb in the room. Don’t expect acoustic panel results, but 4/5 for an acoustic foam tile. After receiving them, I simply soaked them in water, threw them by sets of 8 into the dryer on medium for 30-45 each set, then used 3M double sided tape to place.

I was pleased at first until I reached the bottom of the package when it came in. I count the last 5 panels were crushed at the bottom of them and one of them was completely unusable. I did leave them out for 48 hours but still after they were flat and dead. The ones that did survive work good, however there is too many damaged for me to be okay with it. Maybe it was damaged in the delivery process but either way it came in a box not a bag so I doubt that. If they all came in how they should've been it would be 5 stars for me.

Detailed review (Unpaid/Non Sponsored) I feel that this is a good product and deserves a 5-star rating. Here is why. Pros: -The product measures as advertised. -The product is shipped fast. -This product has a low odor. -This product adheres well with glue spray or other adhesive tapes. -This product is dense and is absorbent. It has multi-groove patterns that will also help absorb a wider range of frequencies vers a typical style pattern. Cons: No many to be honest, but if I have to pick a list of potential drawbacks here we go. -The product is vacuum shrunk to minimize shipping costs. This is a pro when you think of it because the buys save in price, but due to this shipping method you will not pull this out of the box lay it in your space. It will take you about 30-90 minutes depending on if you use a dryer, or if you air dry (would not recommend) but if you do at least 24 hours. Because the seller covers this and it's matched with common sense that these steps will need to be taken., I did not feel that this was worth a negative star but definitely worth noting for those who just read reviews. *If you air dry have the following: 1 A clean lint-free space 2 Space them so they are not touching 3 do not stack them it will warp the foam 4 Make sure your space is ventilated 5 Make sure that you have an absorbent product under the foam. Towels, have them on Rack or something like that. This way all 6 sides can dry.

I’m on the move to create the ultimate white gaming/work station office. I want most everything to be lighter colored which is really hard to do. These panels are close enough for me as I am being realistic in not everything can be shiny bright white anyways. I applied these to walls that had a little grit on them with this “EZLIFEGO” double sided tape I also found on Amazon as well. It holds up remarkably! Just make sure to press the tape on well and press hard on the panel for atleast a few seconds to ensure it’s going to stay on. I plan on getting some pearl white glue to use with my hot glue gun to seal the edges of them together for a more pristine look. I’ll probably end up purchasing atleast a few more packs of these or maybe even a dozen more to complete the entire office I work in. love the way they look and the quality of them seems like it’s really going to help block out noise which is also very important for me as I record music as well.

Tiles seems to work as intended, but note that because there is less flat surface area (due to the raised '3D' portions) it makes it hard to stick to surfaces using 3M tape. I have mine on the ceiling and a few have dropped over time, whereas my flat tiles have stayed firm.

Overall pretty good but 3 out of the 12 panels didn’t quite expand to the shape they were meant to.

Fantastic product. Exactly as described. Not sure why people are having issues with expanding. Soak it in water, ring it out, throw it in the dryer for 20 - 30 mins & voila. I was able to stick them to the wall with stick on velcro strips. Sound absorption is great. Made my home theater sound much better. No more overtones or distorted sounds.

Great product not quite the advertised size. Each tile is actually only 30cm Not 12” huge difference if you measure in imperial and product is actually metric. I ended up 2cm shorter than needed. It was a nightmare to cut in the tiny pieces to fit. Contrary to advertising the product is not that easy to cut. Also huge waste of product which is not cheep. It turned out great in the end except for nightmare installation.
