Benefits of Soundproofing
So you are starting a recording studio and you want to soundproof it? You are not alone. Everyone wants the to record drums at 3am without having to deal with the Men in Blue (or Black if you are an alien). The benefits of soundproofing are amazing when it comes to engineering because you can sit in the isolated control room and listen to exactly what the microphones are picking up. This isolation is makes it much easier to make audio engineering decisions.
Okay, I've been out of school for a while, so my technical jive isn't what it used to be. Work with me hear. This is going to get technical.
In case you didn't know, egg crate foam does absolutely nothing for soundproofing. The same is true for putting carpet on the walls. In fact, egg crate foam and carpet will only effect the acoustics inside your room (which are about 1,000,000 times more important) and are often the worst treatments you could ever make to a room. Do not confuse soundproofing and acoustics. They are two different things entirely and have extremely little to do with each other.
When you say that you want to soundproof a studio, you are basically saying that you want to find a way to keep all that acoustical energy from getting out of your rooms and into your neighbors ears. There are two basic ways of doing that. You can create a barrier that is so dense and thick that the acoustical energy simply won't get through or you can isolate the room so that the acoustical energy has nowhere to go,
Both methods can work well, but depend on your situation.
