18 Pack Acoustic Panels-12"X10"X 0.4" Self-Adhesive Soundproof Wall Panels High-Density Sound Absorbing Panel Acoustic Treatment Panel Used in Home & Offices （Black Hexagon）

50 Pack Acoustic Foam Panels,2"X 12" X 12." I wanted to wait until I purchased my second set to do this review so that it would be honest and accurate. To be clear, these are not for sound proofing...they are for sound absorption just like a sponge absorbing water. They absorb room reflections but do not block sound. They're foam. One example is for vocals to keep the reverb in the room from coming into the mic. This will not keep noise like cars passing by, helicopters flying above, HVAC, or other noise from coming in hence, they will not block sound and soundproof your area. This is something that you as the consumer need to understand and accept BEFORE you purchase these panels. As sound absorption panels, they are good quality panels and work great! Also, to be clear, I am in no way telling, suggesting, or recommending anyone to NOT purchase these panels. They are good quality panels and I have had no issues with them! First thing to know that it clearly says that the adhesive tape does not come with the panels...you have to purchase your own. These are NOT self-adhesive! Second, when using the adhesive tape like 3m, you will need some additional adhesive like Gorilla Glue as foam doesn't always stick to the adhesive tape or the wall. Third, be patient! The best method is to let them set out for at least three days. The first two days is for the "smell" to air out while getting air in. The third day is an extra measure to examine them to see if any forming needs to be done. Pic 1: When then arrived and after I took the package out of the Amazon Box. Pic 2: When I took them out of the main wrapping. There are two vacuum sealed packs. Pic 3: When I took them out of the main wrapping. Since it's now unsealed, air started coming in and they already started expanding. Note: They expand quickly so prepare to get them out of the back quick! Pic 4: What they looked like 5 minutes later. Some expanded in full and some didn't and are deformed. There are two to each "stack". Pic 5: One of the "stacks" that was still somewhat compressed and deformed. Pic 6: After I pulled apart the stack that was still somewhat compressed. One panel. Pic 7. The other panel. Notice on both panel the triangles are deformed. Pic 8: Me beginning to pull the triangles gently. Pic 9: Me fully and gently pulling the triangles gently. As you can see, it's already getting it's form back. For the panels that are deformed, gently pulling the foam to get it to form helps get more air in and they will get their form quicker! This part takes patience! Those that said the panels would not take shape or stay deformed are not doing this to help shape the panels! Pic 10: All 50 Panels laid out and getting air All of this was done within one hour. They still need air out to completely form. Although the directions state 24 hours, it's better to wait 3 days. On my first set, I sprayed some Febreze to further take out the smell and will do the same to these. This does not take away their absorption properties.

Reduced the noise of my built in refrigerator by 75% by placing product on some of the inner cabinet (which was acting like a speaker box.) You only have to cover part of the walls to make it work. This is for sound absorption, not sound proofing. The surface needs to be exposed directly to the sound or noise. Very sturdy but easy to cut to any size with a razor knife. As others have warned, fantastic glue, but it takes precision & patience to tease off the paper backing without removing the glue layer. I found bright light & the tip of a razor knife worked best to separate the paper from the glue. Easy enough to nail or screw in place if you like. Some complained the boards are too thin, but thickness is no issue, since absorption & dispersion takes place only on the surface. I think the bad reviews I’ve seen here are folks trying to soundproof a room (to sound outside) or place the panels behind curtains, etc. They won’t work like that. Would be a great treatment for a music studio or home theatre. I tried several other products before finding this one- it’s a winner- highly recommended for the right application.

Decided to try them again. still not 12 inches but made them work. I did have about 10 that would not stick so that was a letdown. First order was super sticky. I ordered enough to do a small bathroom also but did not have enough because of the nonstick ones, so I am returning some. They are easy to install and help just a bit with noise BUT they are not 12 inches. The are 11.75 and I had 3 areas to put them. Exactly 3 foot and 2 exactly 4 foot. So I ended up with an inch and a half not covered. the length of the ceiling. I would have returned if I had measured before I spent 12 hours up and down a ladder. I am going to get some trim wood to cover the space. Something I didn't expect to have to do. They do look nice and stick very good but if I have to pull them down I will ruin the ceiling. I would recommend them whole heartedly if they were as advertised.

It's a little bit of a challenge to peel the back off but it so worth it. They so cut down on the noise the people above me created. They smell good as well. Well worth the money to get sleep.

I have bought these twice, and the second set developed a terrible mildew smell within a few months just like other reviews have mentioned. I had to take those down and trash them. Both sets were effective, but I used them for acoustic dampening, not soundproofing. First set went in a giant HVAC unit closet that holds a heat pump, and it dampened the sound. I used the adhesive backing and stuck these to the exposed back of drywall, they stick great even being exposed to a range of hot and cold temps. Second set went in a corner of my bedroom where the HVAC heat pump noise echoed. It dampened the echo. I did NOT use the sticky side on the drywall, I was able to use a single nail in the corner of each panel to hold them in place. They did great to cut down the echo, but this was the set that started to smell musty after a few months. I live in the high desert and it's never above 35% humidity indoors, so. This is a problem with the product and how it's packaged and container shipped. It's hit or miss, you won't know for a couple of months if you have a problem with he mold and mildew growing in the tiles. So. If you are putting these up somewhere not in your living space with the understanding these are sound and echo dampening, not sound proofing, go for it. If you want it for your bedroom, find something else that won't be surprisingly smelly in a few months.

So they look great, but they LITERALLY RUIN your wall when you need to take them off, there will be glue residue left and you will have to repaint all the walls. We bought 4 packs and covered three different walls, and it took us around 15 total hours of work to take bulk of the back glue off the walls and we still need to repaint them as there is a residue that is left. We tried heat guns, alcohol, and scraping. The heat and alcohol or other chemicals do not work. Seriously DO NOT BUY unless you don’t care about ruining your walls, which include around 20 minutes per tile of scraping and you will have to repaint the entire wall. Here’s what it looks like after you take them off and these photos are still after hours of scraping. They need to use 3M tape/glue that peels off and does not ruin the glue. DO NOT buy, it’s not worth the several hundred cost to repaint the walls.

Bought this pack twice, very good product. The Walmart double sided acrylic tape works wonders with these panels. They stuck for over a year and would of stayed stuck for many years if we didn't have to move. I also used T Pins where I could to keep them mounted. They sound treat a room beautifully and they look great! Will continue to buy this product if I ever need more.

I bought my mom some "peace and quite" for her birthday... did her laundry room and she loves it. These squares make ceilings super easy and I used 8 on the 32x80 door. Full coverage is much easier IMO but not required. Honestly once you get the first 4 up you'll likely go get whoever else is home to make sure you're not having a stroke. These panels are super bizarre as they literally create a black hole effect in a room you thought was quiet. Even sealed in the Amazon box they somehow absorb sound lol. My dogs LOVE the rooms with these tiles as the cave like stillness is awesome. These were the first batch of self adhesive panels I'd bought. They are on par with the others I've purchased as far as noise canceling/look. You can pay more for slightly nicer looking panels but now that I've heard both side by side I will not be buying the next price point up because they simply aren't worth it for me personally. The adhesive is NO JOKE you get ONE shot. Peel the backer off one edge and lay it in place with one hand under holding the peeled backer and the other hand on top of the tile holding the sticky edge in place. When you got it close peel the backer off and VERY lightly press and make sure you're still lined up. Once you press down these are permanent IMO. The adhesive is on par with self stick flooring. I did absolutely ZERO base prep... just stuckem up. The adhesive is overkill which is what I personally prefer. I used blue painters tape mark my borders and edges. If you are doing full coverage you could easily do a whole room in an hour or two max. A large HD paper cutter will cut these perfectly straight. I cut half way across and then flip it and finish the cut. You absolutely could use a utility knife and a good straight edge, BUT if you're doing a whole room get a large paper cutter. I'm using a Wescott 15in 30 sheet cutter. The trick for straight cuts is the half cut. Honestly this puts so little stress on the cutter you could return it... but that's on you. Just ordered 3 more sets for my Dad's office. He doesn't get excited about much, but they were both blown away.

Se adhiere fácilmente a la pared, ideal para contener el ruido, el producto llegó en la fecha indicada y en buenas condiciones 👍

Very good

I bought these to add some sound proofing to my music room and they do a fantastic job. I think I purchased about 3 bundles of 50 to do the majority of two walls. I put them up on the styrofoam sheets that are up against the concrete foundation so they help with the temperature downstairs as well. At first I tried double sided tape squares but they didn't stay up so I hot glue gunned them on and they won't come off unless I pry them off if I ever move. The pattern looks fantastic and the room now has a studio quality to it that impresses anyone who comes by to jam or visits and gets a tour. Highly recommend this product.

Produto de baixa qualidade. Muito ruim mesmo

جميلة ولكن انصح بالتي فيها تقاسيم داخلية خطوط افقية + عمودية حتى تخفي عيوب التركيب على الجدران لأن بدون ذلك تبرز عيوب التركيب حتى لو كانت طفيفة
