Garage question...

[famous beagle]

Hey guys,

I did a search on this topic and found a few things, but none of them seemed to really address my specific idea. (I also searched on the John Sayers website, but I couldn't really find anything either.)

Here's my deal. My wife and I are moving into a new house, and I'd like to turn the garage into a rehearsal room. It's about 18x18, 8 ft ceiling, concrete floor, and the walls are brick.

There is no concern for sound leaking into the house; my wife is cool with me being loud on occasion. The only thing I want to do is make it quieter for the neighbors' sake.

My idea is to simply build one wall in front of the garage doors. This would use the soundproof-aiding techniques that I've learned about here (the staggered studs, etc.) Would this provide a significant difference in the sound leakage if it were done properly? (I know that I would have a ventilation concern to take care of as well.)

If this would be a good idea, any ball park figures on what it would cost?

Thanks for any input.

if the three other walls around it suck, putting one wall up wont really do much. You will need to basically build a room within a room. It can get pretty expensive if you do it right.

Ok, what is "pretty expensive?" I've heard people talk about things like that, but I've never heard any actual figures. Have any ballpark ideas?

Thanks
