Webetop Acoustic Foam Adhesive Panels 2 inch Thickness Sound Proof Foam Panels 12 Pack Set 2" X 12" X 12" for Sound Insulation Absorbing, 9 Block Mushroom Design Black

Great product. I used it to build a sound proof box for my son's rock tumbler.I tested it with and without the foam an the panels reduced the noise from 60 to 30 decibels. Easy to install as you can cut to size. The stick great and are very soft

They are very good, dont stink much, and really cut the noise down. but that glue on the back is no joke. make sure you got them where u want them. and your gonna need some goo gone to totally get rid of them if your moving

I purchased these panels because:1. No messing with spray adhesive, mess, smell etc.2. To help with echoes inside a small studio, not to miraculously kill all noise. That ain't going to happen.3. Used 24x36 plastic yard signs as backing, also found on Amazon.Be patient with these panels...or all panels for that matter. I purchased 3 packages. They come vacuum packed of course and require time to expand. The instructions state 24-48 hours IIRC. I let them sit for over a week. After 3 days I took a small spray bottle and sprayed the stubborn areas with water....and let them sit. I did not experience any smell coming from these guys at all...but we live on a farm so smells are part of daily life...didn't smell anything.At the end of that week, every panel had expanded perfectly. They're made of foam of course and they are NOT all going to be the same size, a little manipulation may be necessary to adhere them correctly to whatever you choose to mount these puppies on. The adhesive, excellent...no issues, zip, nada.I'll be ordering more, no doubt. Highly recommend.

I no longer have to listen to my LOUD A$$ coworker and his big mouth on the phone all damn day. Praise the Lord Halleluijah!!! ! I bought these as a birthday gift for my husband 😂 to drown him out in his home office — the hollow office door is now padded and now my work from home day is much more peaceful. If you are seeking peace YOU NEED THESE!

I opened this item the same day it arrived. The instructions specifically say to let breath in a well filtrated room not cold but warm for 24 to 72 hours. I left it open as the instructions said but it never really inflated. Seeing how compressed it was (also the type of material) and not knowing how long its been that way, I gave it a little more time and nothing changed. I Don't recommend this item maybe I got a defective item but now seeing the reviews (rookie mistake) I should've listened to the reviews. Currently trying to get a refund. I will update this once I fully get my refund so I can give a refund review.. I bought the grey they were really flat and still currently flat.

Quick fast easy and it works. Time to hang up about 1 1/2 hours. No mess and yes they work. Noice echo is gone. Adhesion is amazing. Make sure you place foam where it will stay. Very effective.1st. Take all items out spay or wet the sponges. Let sit outside for best results 3 days they will rise like a load of bread. Make sure you let them sit out and fully dry. Soaking the tops does not effect the glue. Then hang. All were fully risen. Looks so professional.

Easy to put up (most other brands come without the adhesion so this was great). Super thick. Muffled my sons game room GREATLY!

Just redid my basement. It has no furniture to absorb noise and tile floor. I put these up and my roommates and friends all noticed a noticeable difference. Just 10 on them made it way better downstairs.
