12 Pack Acoustic Foam Panels Studio Soundproofing Wedges 12"x12"x1" Noise Dampening Sound Insulation for Home Ceiling, White

so thin and squished. I didn't even use these. They would look crazy on the wall. Can't speak to usage. No adhesive and I cant even think of how I would get these up.

This must be effective since my tenant isn't complaining about noise anymore. I used the double-sided tape (not included) and installed about 3 feet above floor level. They look nice installed as pictured and appear to be durable. I planned to get another set to increase the size if my tenant complained but so far not needed to increase the size, but the size seems perfect.

I ordered a lot of these to insulate and sound proof a travel trailer. I used spray on adhesive as advised and they fell down. Half of them never opened up and stayed flat. Now they are in a trash bag..

A warning: the white version of this product will yellow within a few months, and it'll look like you've been smoking cigarettes around it. I chose white in an effort to keep my home studio lighter and brighter, but it backfired... at some point I'll replace these with black foam panels because it's become a pretty unattractive shade.The foam works for sound absorption, although some packages arrived with one side compressed to a point that the foam would not expand evenly. It sticks pretty well to the Bakulala double-sided adhesive squares (also purchased on Amazon).

It arrives in a shrink wrapped sleeve. Then you open it and it doesn't change from being basically a stack of thin pancakes. The pictures in the advertising are a complete lie, the cuts and the size of the foam is nothing like what they send. They tell you then to soak each sleeve with water and then blow dry it, but soaking it does nothing to lift the foam.Also the foam is discolored, not pure white. Some panels are white and some are yellowish on the edge.Also, several of the panels are very thin and despite being filled with water won't expand because there is nothing to expand.Worst product I have ever purchased on Amazon.Don't. Just don't.

I read all of the reviews before purchasing the tiles. I still gave it a shot not knowing what I was going to do to resurrect the bulkyness of the panels. I then Googled what others did. All you need is a blow dryer on high heat. DO NOT DUNK THEM IN WATER. Take a panel and start blow drying them. I literally was placing the drying so close, but keep it in motion. Otherwise it burns! I did the back and front until it puffed out again. I also did each ridge. It was so great, just took a little patience and effort. Try now to blow dry near your fingers. They are great and it works. Please give it a try. I wish the seller would include the video I Googled for instructions.

I understand why they ship these flattened with the air removed, because once they are fluffed back up they get very large and the shipping costs would be extravagant. That said, it does require a little work to bring them back to fullness.After removing the packaging, peel the squished-together layers of foam apart. Dunk them in a bucket or sink full of WARM water, squeezing and massaging them under the water, taking them out and squeezing the water out, etc repeatedly until they fluff back up. Squeeze them as dry as possible, then tumble in a LOW HEAT clothes dryer for 15 minutes, and after that either air dry them in a room of your house or put the dryer on NO HEAT/ AIR DRY setting and keep them tumbling until they are done.I just got them today and they look okay for now, after getting the above treatment. If something happens in the future I can post another review.

First, it doesn't work at all. The product is thinner than the advertising photos. Literally no sound was absorbed or reflected. Second, it turned yellow within two days.DEFINITELY NOT WORTH THE PURCHASE
