52 Pack 1" x 12" x 12" Black/purple Acoustic Wedge Studio Foam Sound Absorption Wall Panels (black/purple)

I ordered these more to cover the walls, and add some echo cancellation, as I live in a historical building that is just starting to do renovations, so my walls has cracks, they are uneven and the paint isn't the best looking, but not tons I can do about it as I rent. Since i have a Youtube studio set up in my room, I figured the best way to make it look more modern was acoustic panels. They do also help with echo cancellation, that "stadium" type of sound, but they don't block noise out from other areas, they aren't for soundproofing, they are designed to stop sound from bouncing around, which does quiet things, such as a window fan, that has it's sound bounced back from the opposite wall.They come VERY compressed. maybe 12 inches thick, and I was worried as it said it could take 48 hours to expand, unless you soak them in water, then it can be reduced to 1-5 hours. However, as soon as I opened the package, POOF they expanded nicely and were pretty much good to go, a few panels were still squished, but they are good enough to go on the wall. The pictures I have attached are from under 60 seconds after opening the package up...One thing, is that they do stink... they smell like really strong mildew, and my skin felt a bit itchy where I had touched them, then myself, but it went away fast. The smell is not mildew, just the smell from the polymer. This is the same foam you get in like a cheap mic windscreen cover, or cheap earbud covers. very fluffy and not rigid. I put mine by a window with the fan pulling air out, and it went away within an hour, anyone that has ordered a mattress recently will be familiar with the process.The panels are large also, very large.

Was just what I was ordering for my studio Iive room.

They help with the sound in my studio in my basment. Wish they were a litte thicker. Overall im happy

The double sided tape pads will not hold up but if you just put a little super glue on some of the pads the foam won't fall off

If your looking to competely spund proof your room that's not gonna happen with this but it does compress the sound a bit and looks fantastic!

No noise cancelling. I got it for 2 reasons. 1)I work from home and my 4 yr old grandson is loud. 2) I do an online radio show and my grandson is loud. I'm going to have to double or triple layer to get what I need.

It does not cancel out noise but its good for decorations. Easy to cut color blue is different blue but I love it

Works alright for the money definitely would recommend the wash and dry method of expanding them and use spray glue I couldn't get double stick tape to hold definitely would still need larger bass traps but overall good
