jam room in garage - resilient channel ??
« on: September 13, 2010, 05:20:37 PM »
Hi all.. a couple years ago we started builing a room inside my garage to jam in.. that project got delayed and I want to get it finished up for the winter.

the garage itself is about 25x25'.  The room is in a outside corner and is about 10x12'.  the garage is not insulated.  the room is just built using 2 of the exterior walls (2x6s) with 2 other walls added inside (2x4s).  Next step is to insulate the room with some safe and sound insultation I already have and drywall.  I have 3/4" drywall.  My debate at the moment is whether or not I should use resillient channel.  Well it make a noticeable difference in cutting down the sound outside?

I realize this won't be a sound proof room, but I'd like to cut down as much of the sound as possible with what I already have going, without spending a ton of money.  So any advice would be greatly appreciated!! :D

cheers!
Matt.

YES use resillient channel or clips and channel. Decoupling is the best reduction value.

any other inexpensive suggestions for cutting down on noise leak? 

does using clips add much?

also, if I'm using resilient channel, how should I mount the electrical outlets?

Thanks,
Matt.

Clips and hat channel work far better than resillient channel. You will need to move the box down to compensate for the channel.You should use putty pads for the back of all outlets and the drywall can not make contact to the box, 1/8" gap filled with acoustical caulk.

Using clips and channel can get you upwards of 61 STC, with a couple other materials included.
Resilient channel will deliver 44-47 STC,  with a couple other materials included.
