Fstop Labs Acoustic Foam Panels 1" X 12" X 12" Self-adhesive Acoustic Studio Wedge Tiles, Sound Panels wedges Soundproof Foam Padding Sound Insulation Absorbing Home and Office

Awesome product works better than i thought it might. I built a shop vac cabinet for my CNC routers, to try to quiet down the sound of the shop vac; nothing is more annoying than the sound of a vacuum cleaner running the whole time your routers are running lol. Figuring the sound would really echo inside of the cabinet and turn it into a speaker so i bought these in anticipation of that. Sure enough once i had it done i was getting >85 dB, but once I lined the inside of the cabinet with the panels the sound dropped to >60 which is hardly noticeable over the rest of the tools. I do wish the adhesive was a bit stronger, but once you have pressed it firmly into place (maybe roll it out) i think it will be fine. I'll be buying more for sure

I bought this mostly for the decoration if I'm honest. It was cheap enough that I figured there would be no audible benefits, but it did remove a slight echo in the area of the room I used it and I'm pleasantly surprised about that. I had to soak them all in hot water, ring them out and let them dry thoroughly with a dehumidifier before installing.

The material is very good, it enhanced my bedroom studio. Love them.

I read several reviews and was almost thrown off by the statements that the acoustic panels did not expand fully. Instead, I opted to get 3 different products to play it safe and ended up liking this one the most... though expansion is something you have to plan for.When you get the product, it is vacuum sealed, so they are flat to start and need time to expand. I opened the package, laid the panels out and let it sit over night. Some looked good, some looked deformed with only parts expanding. As I had time and I really liked the ones that had expanded, I played around with them.Given time, they should all expand, but it's a dense foam and sometimes a little help is needed. For one that just wouldn't budge, I wet down the side that was not expanding and let it sit for a day or so. Popped right out.Bottom lineIf you have some flexibility, the product was the best at reducing noise of the ones I ordered, the best value, and very easy to work with once they were expanded. That said, if you are in a hurry or don't have the space to lay out the panels so they can expand, you may want to consider other products or buy spare packages.

Pictures above show what they're like before and after letting them expand for a few days.Pro's:-9 of 12 expanded.-the ones that work are fluffy and look nice-there's not much of an echo anymoreCon's:-3 of 12 were defective-they're not the same size, not 2" thick, as advertised-they don't sound proof, as advertised, you'd probably have to cover the whole wall and feel like you're living in a padded cell so you might as well fork out the funds for sound proofing panels that look nicerIn all: I like them for now, they are good enough until I can get something nicer. They do remove the echo in the new place. They're really not worth their price, though. You could easily buy some foam and use double sided sticky tape for a lot cheaper and more efficiently.

I essentially bought several different types/brands of acoustic foam panels because I was worried about different in quality and delivery. I bought1. "3 of New Level 6 Pack- Acoustic Panels Studio Foam Egg Crate 2" X 12" X 12"2. "12 Pack Set Acoustic Foam Panels, Studio Wedge Tiles, 2" X 12" X 12" Acoustic Foam Sound Absorption Pyramid Studio Treatment Wall Panels"3. "12 Pack Set Acoustic Panels, 2" X 12" X 12" Acoustic Foam Panels, Studio Wedge Tiles, Sound Panels wedges Soundproof Sound Insulation Absorbing"The first is from "Urban Mall", and the other two are from "F.Stop Labs". This review is comparing item #2 with item #1.First, both #2 and #3 arrived together, in a single box, compressed into individual 12-pack bags as can be seen in the first picture that compares the foam panel with a bag next to it. That panel in the first picture is a panel that was taken out of the bag, aired for Sunday, Monday, and Tuesday (72 hours). After 3 days the foam was all compressed, and looked really bad. It did not uncompress at all. That was the first method the seller recommended to use. Then I soaked the panel in water, squeezed the water out, and let it air dry over night. The next morning it was still damp, but the overall shape was better.The second picture compares a panel that was uncompressed for 3 days (on the right) with a panel that was left wet and then air dried (on the right).I would not recommend you to get #2 or #3 because you will have to wet each panel, squeeze it, and then find space to let it dry - that will take quite a large space. So that is one reason why not to get it.Second reason why not to get these panels is because of the quality. As you can see in the last picture, the panels arrive wrinkled, and have additional damage cuts on the back side.Third reason why not to get these is because of the product specification is not matching what you will get. I ordered the 2 inch thickness foam panels. Letting the panel air decompress will bring it to about 1.5" at best. Wetting the panels and then drying them will generate a better shape, but will still give you panels with thickness of 0.75" at the lower end, and 1.75" at the higher side. Not even close to the 2.0" that was ordered.
