18 Pack Gray Acoustic Panels 12"X12"X 0.4" Soundproof Wall Panels Wall Decoration Sound Absorbing Panel High-Density Sound Deadening Panels Acoustic Treatment Panel For Home Studio

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.

My son loved these will probably get another pack definitely helped reduce sound n he’s a drummer just wish it came with some adhesive

Why did you pick this product vs others?:AffordabilityEase of installation:So time consuming and they do not come with the tapeNoise level:Helps with sound blocking. Muffles things pretty wellDurability:They treat very easily. If you have small kids or animals I would keep this in mindSmell:No smell

Before purchasing, I'd read about how strong the adhesive is, and how difficult it is to remove. A few months ago, I rearranged my home office. I tried using heat to soften the glue, for easy removal. Nope. It just curled up, so i left it alone. On 5/16/25 (a few weeks ago), my home was destroyed by an EF4 in London, KY. While going through the debris, I found a panel, still attached to sheetrock. It gave me a chuckle, and I vowed to write a review.

They are great. Out of the package they bag an to expand immediately. I was a little worried that some were too smashed but they expanded perfectly. They are the full 2”s and they also stiffen up good.The first 3 pics are after 24hrs. The last 2 are are right after opening.My only issue was that they are extra black and the ridges are smaller than my other/older foam panels from the foam factory. The last pic shows the difference with other panels.They do exactly what they are supposed to which is absorb reflections and frequencies bouncing around the room.I would definitely recommend and purchase again.

I have a budget home theater room and used the foam panels to reduce noise reflection, 'echoes', and to improve sound clarity. The adhesive works great, to date non of the panels have fallen. Anyone purchasing, if budget allows, should buy the 2 inch or thicker. But, these works well for me.

Despite trying all processes to decompress the foam, it ended up being a long and involved process, but hey it's fine now. They say to put them in water (they are basically sponge material) or let them sit and they will completely expand. I can tell you that neither process works. I ended up having to hand pull the foam into shape, but everything is OK now.

Worked but strong chemical smell
