Another Jamspace Soundproofing Question
« on: January 28, 2006, 09:39:28 PM »
Hey all,
You're probably getting really sick and tired of hearing all these same questions, but I'm in dire need of help so I thought I'd ask the boyeez who know it best...

I'm currently in a hardcore band that is starting to jam in my basement, It's not soundproofed at all... In fact It's still undeveloped which maybe might make it easier to install some sort fo insulation... but anyways, I want to know what's an effective way of soundproofing a room, If you could tell me all the things I need to do that would be great!

It's in my basement so the walls are half under soil, and other than that I just wanna make it a dope room! I'm not toooo tooo worried about pricing, but as always, the cheaper, the better... as long as it's effective.

Would anyone be able to just tell me a list of materials I need, reccomended brands, anything I need to know to make the room as deafened as possible. We do have a PA in the room, I dunno if this changes anything... I really only need to know what materials to look for, and how to do the basics... I can figure out the rest is a cinch!.

Thanks so much for considering this!

The most effective way to isolate sound would be to build a room inside a room. If you have the money build your walls out of cinderblocks and fill the cavities with sand. You can find many resources on the net about building a room inside a room, but the theory behind the construction is building walls and a ceiling that is completely independent from the existing structure and a "floating" floor. Lay down a roll of neoprene rubber, frame the floor and use 2 sheets of plywood to build the floor with rockwool in the open cavities under the plywood. This of course is if you have the budget and want to do everything you can to isolate sound.

Hi Skish,

Here's what you do.  Put bonded cotton insulation inside walls/ceiling - cost $0.83/sq ft.  Staple MLV directly to studs/joists to make continuous sound barrier - cost $1.47/sq ft.  Add isolation tape over MLV at studs, sole & top plate, joists anter caulk MLV perimeter - cost around $0.23/sq ft.  Screw finish dry wall through to studs/joists - cost local supply.  This will give you a 75+ STC wall/ceiling assembly!!  If you want to really knock down loud bass vibes, add a layer of Green Glue and second layer dry wall - cost $0.93/sq ft Green Glue plus local dry wall cost.
