I was hoping someone would help me out without having to look through the 4000+ posts in the master acoustics thread. I've got an up and coming theater room that's in a finished 2 car garage with a carpet over concrete floor. The sound is pretty good, but the room is right next to a master bedroom. It's only separated by single studded drywall wall. Would adding more drywall help that much or would I need to do something more? My 18" sub is just too much for my wife even when it's not that loud.

I know going completely silent in the bedroom would be more money than I can afford, so I'd like to know some options from best to worst scenario.


Thanks

good read:

So I think with the options and not wanting to throw thousands of dollars into it I may add another layer of studs, staggered, and add some channel to hold a new layer of dry wall off of the studs. This should help contain the vibrations and a good portion of the bass in the room with me. It won't do it all, but I am sure it's better than what I have now. If I do all the work I would be out a couple hundred dollars. Maybe a bit more but not too much.

Decent?

You would not need the channel if the studs are staggered.

Small amount of fiberglass would help

Make each side of the wall as heavy as possible

I thought the channel would help distribute the vibration away from the studs and keep that wall separated from the rest of the room.

Could I just add the channel and not stagger the studs?

Nope. This also means we should discuss "channel"

If by "channel" you mean 7/8" Drywall Furring Channel (as is used with resilient clips), then used by itself it will not decouple. It's also too stiff in that application.

If by "channel" you mean Resilient Channel (also known as RC-1, Chicago Bar, and Resilient Bar) then in a perfect scenario it would perform the desired decoupling. We don't have a perfect scenario, unfortunately. The channel is not accountable and suitable for our needs. I can elaborate if anyone's interested.

I would suggest you go the staggered stud route as planned. Again, just drop the channel.

I was talking about resilient channel. I will go with the staggered studs.

Busy wise it will be probably summer befor I can get started on it, but I am sure my wife would like the finished product.

Good luck and keep us posted

Sure will, and thanks for the good info.
