Standing waves, room modes, acoustic reflections — These are all just fancy ways of talking about why your sound sucks if you don't have the right acoustic treatment. The bottom line is that you're going to need to do something about those blank walls that bounce sound around your studio. If you've been looking into it, you've probably noticed that most companies charge an arm, a leg, and maybe a kidney or two for acoustic treatment. So what's the alternative, egg cartons? Only if you want to turn your studio into a giant blazing deathtrap. Luckily, the wonderful people at aura Lex sleep better at night by offering excellent, safe, and easy-to-install studio foam treatment. With just a pack or two of studio foam on your walls, you'll hear a night-and-day difference in your sound. So, say goodbye to bad reflections, and say Hello to aura Lex studio foam.

There are two different types of sound treatment, and I really mean they're TOTALLY DIFFERENT: (I'll explain)
1) Sound Proofing
2) Acoustic Sound Treatment
1) Sound proofing: This is when you're trying to make it so no one outside a room hears what goes on inside the room, and vice versa. This foam is NOT FOR THIS PURPOSE. This foam will NOT make your studio/room sound proof, so please don't give it a bad rating if you used it for the wrong purpose.
2) Acoustic Sound Treatment: This is what this foam is for. It will catch sound frequencies (specially high and mid frequencies, but definitely not the bass) when they try to bounce on the walls and will absorb a little, and scatter a little in order to reduce the echo or reverberation effect. This will in turn make your studio/room sound "dead" which gives your ears a chance to hear your mix a lot more accurately, and without the room adding it's own sound effect to your creations.
In laymen's terms, it absorbs some of the sound because it is porous and waves that try to go through bounce so much they lose momentum and die, and the waves that don't go through get broken up by the pyramid shapes and sent back weaker, and spread out.
With that said, there are better ways of treating a studio than this foam. I recommend you look into Fiberglass Panels made with "Owens Corning 703" a quick google search will yield tutorials on how to make these bad boys yourself, and they're many times better than this foam, I guarantee it. I personally use this foam for the ceiling of my studio, and in my recording booth for the ceiling, and a small part of the wall lining. I use the Fiberglass panels for the walls, this combination of the two has yielded Amazing results.
How to Adhere: This is a very common question in forums, and every person will give you a different method. Here are 2 of experiences with them, and how I managed to get them on.
First attempt - The not so good 3M Super 77 Multipurpose Adhesive Spray method:
I wanted to be able to remove them when I move, so at first I tried this 3M Super 77 and sprayed it on the back of the wedges, then put it on the ceiling. That was a DISASTER. I came back the next day to find all of them all on the floor, and I had used the spray generously. To fix this, I sprayed the wedges again, and I also sprayed the area of the ceiling where the blocks are going to be, with adhesive on both ends, it works a lot better.
BIG FAT RED WARNING: This spray creates a mist, that could potentially fall on your equipment, and make it sticky for a good while, so if you go with this spray, cover the gear below with newspaper while you spray it on the ceiling, and spray the foam blocks into a piece of cardboard, or outside.
The second and better method - 3M High-Strength 90 Spray Adhesive:
This spray is a lot stronger, and it shoots a kind of silly string, so it doesn't create the sticky mist that other one does, thus it's a lot safer to use in your studio with all your expensive gear. The only downside, is that once you stick it, it's a lot harder to take off the wall, albeit not impossible. To use this spray you MUST SPRAY BOTH WALL AND FOAM, otherwise it will not stick.
Another Tip: This foam works better when you change the direction of the pyramids with every block, as to create this pattern:
Please let me know if there's anything that should be added, or corrected here. I became an Amazon reviewer to help people make the right decision for them, just like many other reviewers have helped me. Also, if you think this has been helpful, please vote it so it will appear first, and others can find it easier.
Hopefully if you are spending this much money on acoustic foam you already know that it doesn't make a room sound-proof. The intent of acoustic foam like this is to reduce reverb, echo and other unwanted noise in the room you are recording or listening to the audio in. If that sounds foreign, do more research before purchasing. If you buy these and expect to play the drums or crank your guitar up to 11 without the neighbors hearing it at all, you will be disappointed.
Also bass become tight and smooth and actually I reduced 2 dB and changed crossovers. But we should not over done . If you your going kill the sound
Would recommend this to anyone looking to convert a room into a VO studio
