TroyStudio Acoustic Studio Absorption Foam Panel - Broadband Sound Absorber - Periodic Groove Structure - 12'' X 12'' X 2'', PACK of 6

I love these panels , so I've decided to treat the whole space. They do expand fine if unpacked and left over night. There is a bit of an odor that dissipates over a few days. I also like how they look on the wall after some 3M tape and some patience.

I expected this to be trash. I needed an add-on to get free overnight shipping and thought why not. My friend use to have a recording studio in the attic where we lived and it was pretty well treated against reflections. He had a nice set up with even bass traps and stuff. Nearly 20k+ equipment in a college dorm.I knew I’d likely never have a setup like that so I got a Shure SM7b, which is a dynamic mic. It has great off-axis rejection on nearly every side except behind. This means it works pretty well in less treated rooms and is good at blocking ambient noise. I used to live in line of an airport and a busy Highway, so that was important.All this to say: I thought these would do nothing, but they immediately reduced reflections. My noise sounds less boxy and almost echo-y. A much dryer, crisp sound. I might buy more of these panels lol.A little goes a long way, but I didn’t really need to stop side reflections. Put a few of these behind and to the side of you and you’ll be surprised.I didn’t soak them in water or wait very long. They immediately popped up and seemed like the right dimensions. I left them a few hours and they looked the same. Basically zero smell.I left them overnight just in case, but they still looked fully expanded and didn’t smell.I used 3M medium command strips to hang them up. They are super light so that might even be overkill. But it was a lot easier and cheaper than spray or double-sided tape.These are a great value and for my purposes did more than enough. If you want something to isolate sound or sound proofing, this is not the product. But if you want to minimize noise bouncing everywhere, this is great. Plan to get a lot more than me if you have a bare room with no furniture or use a condenser mic.

Good one. Looks good. 6 is not enough. Need lots more to absorb sound

I am somewhat disappointed with this purchase. The material does not absorb sound as I was hoping. It's ineffective.

Si las medidas son falsas qué esperar de los demás.
