Just embarked on my HT install and have a framing question.

Quick background, I'm concerned with reducing noice up through the ceiling as my master bedroom is directly above the home theater. I certainly don't want to be yelled at constantly to turn it down! I will be doing some sort of sound deadening/etc on the ceiling.

My Concrete exterior walls have concrete pilasters so I bumped out the framing 7" from the exterior wall. Already installed XPS foam insulation to concrete block and plan on having Roxul or equivalent unfaced R13 in the stud wall. I have the wall anchored to the floor using seam sealer and a treated 2x4.

My question is... Should I brace the interior wall by attaching brackets using tapcon screws to the concrete wall? Or attach the wall up to the floor joists. I attached the wall to the joists for now to brace it.

I suppose I could frame a whole new floating ceiling... I'd have to look into that a bit...

Ideas?

Do this, don't think about it just do it. Of course you need to address the walls and many other issues.

Attach the top of the new wall to the floor joists. I think there is a way to do this using clips in order to cut down sound transmission through the framing but I'm not sure what kind of clip you would use. Ted White at the Soundproofingcompany.com could undoubtedly tell you.

If you haven't seen the articles at the soundproofingcompany.com, you should really spend an afternoon reading them. There's an article on soundproofing a ceiling and one on soundproofing walls that would be especially timely for you to read.

Thanks for the input guys.

I've been reading all sorts of stuff... Soundproofingcompany.com does have good info. I was aware of the clips for holding drywall through furring channel, but not aware they could be used to hold the walls themselves.

Thanks.

This is mainly to help with foot fall from above isn't it? rather than keeping noise in the room?

We have our master bed above ours as well and its got a massive bed in it biggrin.gif which you cant walk over so there isn't too many spots where foot fall is/would be an issue.......I suppose at the end of the day its only going to help right? so just do it....
