soundproofing

[analogcreature]

my band is starting to play more and more in my basement area we have made fro rehearsal and recording, i need to know a averagely priced, extremly effective way of keep the sound in the room. we have alot of tubing and vents and stuff above us going through the ceiling. we are surrounded by a brick wall on 2 sides of the room, and a plywood barrier type wall on the other 2 sides of the room. basically the folks need to hear little to no noise or bass from upstairs

Soundproofing is very hard. As far as I know you'd have to build up a room-within-a-room kind of thing. The tutorials I've read suggest putting up wooden batons, filling around them with Rockwool insulation, then covering with thick plywood (several layers even).
There's quite a few tutorials around - www.soundonsound.com should have some.

This page gives a quick overview of what's involved and where to start

Room-within-a-room is probably the best way.

Heavy Drapes with lots of folds on the sides, but for the ceiling I'm stumped. You could probably do the same though, hang them from the corners of the room.

It will not help much though if you have pipes going through the ceiling to upstairs.

That's NOT going to be a recording studio though.

If you really mean no noise, it would be cheaper to get an electronic drum kit, mixer, and a few amp modelers and put everyone in headphones. the kind of construction necessary to allow no noise in the same house is prohibitive.

I concur with the last statement, low frequencies are nearly impossible to stop without spending huge amounts of money. For ceilings you need complete isolation via a channel that would attach to the bottom of the joists separated from the wood by a foam barrier, then you need lots of insulation or rock wool up in the joists, all covered with 3 layers of different thickness drywall with all the seems made airtight by some soundproof caulking. If you have any holes at all in the room, that noise is going to get out and it reduces your dB reduction by huge amounts. Your doors have to be air tight, no outlet knockouts in the room, it all makes a big difference in the propagation of those frequencies. If you have wood on wood connections that are exposed to the frequencies, the sound will travel everywhere.

Lots of people who know what they're doing over there...but it's going to cost you tons of money to do what you want to do.
