How to minimize vibrations in a stud wall.

post #1 of 6
Thread Starter 
Ok I have 2 pretty basic questions. I've done some research but honestly my eyes are starting to dry up looking at this computer screen so much lol. When I stud frame my theater do I have the top plates nailed to the ceiling joists? That seems counter productive to me. I don't want any vibration or such going up the walls and in to the room above. I am decoupling the ceiling and doing DD+GG for the ceiling. If not how much of a gap should there be between the top plate and the ceiling joist and should this be acoustically sealed?

Also the stud framing for the outside walls will not be directly on the concrete as I have 2" xps rigid board placed up against the concrete ceiling joist to floor for insulation purposes. Thank you.

Would anyone have a diagram or picture showing how to properly build this, I'm much more a visual learner hehe.

You're right - it is counter productive. You can do several different things. One is to go ahead and coupe the walls to the ceiling (overhead floor) joists - traditional framing - and rely on the clips and channel to keep the energy out of the framing altogether. This is not a bad option, but not the best. You could also use a different sort of clip to connect the wall to the joists. I forget the name of that sort of clip, but they're available (I think the IB-3 bracket is good choice for this purpose, but I'm not sure). This is a better option.

A third option is the one I chose. I built my walls so that they were too short to reach the joists, and then in the joist bays from the floor overhead, I installed new ceiling joists. This framed structure is entirely independent from any other framing in my house. Here's a picture of the double top plate, a floor joist, and some plumbing from an upstairs bathroom.


You can read about the way I did it and some of my troubles in my build thread, linked in my signature.

Very interesting thank you. Can someone confirm if those IB-3 brackets from soundproofingcompany.com are what I need and how many I would need. Sq. footage of the room is 216'.

The IB-3 brackets are spaced every 4-5 feet to connect the top plate to the joists. When framing a new wall perpendicular to the joists, you may need to install blocking between the joists to provide attachment points.

The walls you build next to foundation should not touch the foundation or any foam board you have attached to the foundation. Leave a 1" gap if possible to avoid any contact.

Send me a PM with your email and I'll send you the SIM on the IB-3.

Yes, they are. Well, it's not hard to figure out. You want an IB3 clip about every 4 ft max. and one near each end of the wall, about 6 inches from the ends is what I did. So, figure out the length of each of your 4 walls for the room and add up the clips. It's always better to have a few more on hand anyways. Ted from The Sound Proofing Co. is here to help. Besides, once you order products from them you get a very detailed set up instructions on how to install w/ pictures to help you.

You seem to have quite a few threads going for your theater build. Do us all a favor and condense it down to one thread where it's easier to keep track of. We can then check in to see the progress of your build and answer questions you might have. Title it something like "mijottter Home Theater Build", and post your pics, proposed room dimensions, concerns and any questions you might have in that thread.
