I think I have an easy room to sound proof
I have a 12x12 (9' ceiling) room that I am needing to soundproof. Used primarily for drum recording/band practice. It is located in the basement, underground with no windows. 3 of the 4 walls are 8" concrete with dirt on the other side. I have sound foam to deaden the room already(the expensive stuff at MF - for what its worth). There is a living room directly above and a recroom on the other side of the wall. Needs to be quiet for people to still live while I work. :).
I was planning on splitting my 2x6 floor plate and using silicone. Maybe splitting all my studs and siliconing them. Siliconing the sheetrock to the studs then another layer or 5/8" sheetrock silconed to the other piece. I assume I would do this to the ceiling as well. I might even make it a floating floor.
Does this seem like a good way to sound proof this room? 3 or 4 walls should be considered sound proof already. 1 wall and the ceiling need to be as quiet as possible. What would you recommend?
Thanks
Justin

To make a room soundproof (meaning to keep outside noises from coming in and inside noises from getting out), you need to build a room within the room. You have to consider the week point in the room which is the area above your walls, where the floor joists rest, and the decking above them. The bass is going to travel in the concrete wall, and vibrate the rest of the house. The bass is going to vibrate the floor joists. It is going to vent through the plywood deck above them.
You a floor that floats, with walls built on that floor, or walls built on isolators and a floor built on the inside of them, and then a ceiling that is floating, all air tight. That's the only way. Anything else is an expensive, ineffective bandaid.

Foam does not sound proof BTW. Foam is an acoustic treatment to absorb some highs, but that is about it.
Since the biggest issue for you is bass and low mids, you will only soundproof by building and floating a complete room within the room.
For more reasonable considerations that will not be perfect, nore complete soundproofing, look up http://www.johnlsayers.com and read his stuff. That will get you going in the right direction.
