My wife will kill me if our new ht room is not soundproof!!

[TYLER JC]

Ok everyone, I have been reading and reading on the many different ways to soundproof a home theatre. I was pretty sure I knew what I was going to do and then I read stickies post. Now I feel like I have to spend 25g's to get this right, anything else will be a WASTE OF TIME.
I am planning a new addition to make room for our growing family with the added space I am going to convert our old family room into a multipurpose media room. I am most concerned about not leaking sound outside the room so people can have a civilized conversation or sleep while whoever (mainly me) blares my 7.1 surround sound, base laden Definitive Mythos!! The Room is roughly 17 by 13 and it has one exterior wall that is a 12 inch thick log wall. One bedroom will be above so I am wondering what the best soundproof ceiling treatment will be that will still allow me some wiring access. I was also planning on staggered stud walls with roxul in between and using rci clips to hang some quiet rock 5/8 thick drywall.The room is pretty central to the house. I am not looking for perfection just the best soundproofing I can get for the rest of the house. Could someone help me out with suggestions!!

I was at the building supply store the other day and they had a box in the insulation section.

Like a treasure chest.

It said open me. Inside was a boom box playing really loud surrounded by some Owens Corning Quiet Zone.

then I closed it.

Couldn't hear a thing.

Probably won't help with the deep bass though.

How large was that box? What was it sitting on? Any power outlets, audio outlets attached to that box? Or, totally sealed? I doubt it was a credible demo of a room being soundproofed.

Alert to police that you will be dead in the near future

Hard to soundproof and isolate an HT room, especially the low frequencies. You will need special doors and sealed entries, all outlets sealed as sound will penetrate it, heating ducts treated, walls well insulated and on it goes.

A little constructive help please!

Seriously, wondering if it is a waste of time to spend the money on staggerred studs, roxul, quiet rock, green glue, genie or resilient channel clips. Will any of this help or is it a waste of money.

so do I. the box was maybe 5' x 3' x 3'?

Either way, the quiet zone stuff apparently isn't even anything special, just regular insulation with specific packaging.

My best advice is to contact GIK Acoustics. http://www.gikacoustics.com/contact_us.html

or http://www.soundproofingcompany.com/blog/archives/author/tedwhite

Ted White and Glen are the best guys to get info from on this. I can get them in contact with you if you like.

If you cruise a bunch of my old posts I went through a process of trying to figure this out. What I ended up with in my basement finish:

- Staggered stud walls to anywhere that was not an exterior concrete wall
- RSIC-1 clips and resiliant channeling on all walls
- RSIC-DC04X2 for the drop ceiling
- Solid core door
- Offset outlets on each side of a wall
- double insulation in the ceiling joists
- floor and riser on U-boats and decoupled from the walls
- likely some other stuff I have forgotten

The end result is nothing gets in or out - EXCEPT the deep bass hits from the subwoofer. I unfortunately didn't have the space (mostly due to ceiling height) to do a room within a room. Aurelx has some great info on construction techniques.

Good luck and keep asking questions.

If the floor is a slab, I'd leave it alone. It's so massive.

Decouple the walls with a double stud system if possible. If not then stagger. In any event, the walls will be decoupled and will not benefit from the use of clips and channels. Preferable to decouple walls via framing rather than using clips.

Clips and chanel on the ceiling is a great idea.

Use standard R13 fiberlass in the walls, R19 in the ceiling. I would not recommend using more insulation, or spending 1 penny more on an insulation that said "acoustic" on the label.

Now you want the walls and ceiling to be as heavy as possible. Standard 5/8" drywall from Home Depot is $7 a shet and very heavy. Use two layers.

Lastly, damp the drywall with a quality damping compound.

After that, you would turn your attention to the doors, ventilation and outlets. All of these areas can allow sound to leak (flank) out of the room. Treating these areas isn't necessarily difficult, but are all easier to deal with if you address before construction begins.
