Sound Proof Construction Techniques

[Timmy Tucker]

For example, how do you hang gypsum board on the studs without coupling it?

Sac Ducs recommendation of hat channel and isolated clips is probably the best method for gyp isolation. But they are $$$, almost $9 a clip and that doesn't include the hat channel.


U-Boats are much more economical but provide less isolation as the sheetrock is still coupled to the studs through the screws. At one time they were the industry standard for budget-friendly rooms. I have used them in the past with great success. They run about $35-$40 for 25 pcs.



I have no experience with Green Glue, but it appears to be a great product and easy to use. Given the opportunity, I would definitely not hesitate to try it.

The Green glue is essentially Quietrock that you make yourself. Besides being less expensive it is better because you can alternate the seems of the drywall during installation to provide a better seal.

It is messy so if you install it or have someone else install it be prepared to throw away those clothes.

Hi All,

Bit of a random question but I am wondering if anyone has had experience using quietrock or Acoustiblok for the purposes of creating a quiet office/listening space?

Well, we have proven once again there are no random questions on NMC, or shortage of people to answer them

"I'm excavating a third century Mayan ruin, and I am really having a hard time removing inorganic material ..."

What is the pH of the soil?  Metallic or no?  What kind of paleodemography are we talking?

"I am in the middle of spine surgery, I could use some help.  ACDF, allograft, myelogram showed slight stenosis, some osteophytes.  Anterior approach..."

Posterior approach FTW.  I know you're going to say late kyphosis from disc space collapse or radiculopathy from foraminal narrowing but, hey, this protocol has worked for me.

"I am building a space shuttle out of stuff in my garage"

Space plane or shuttle?  And can I come over and help?

Some great advice here

I looked into the green glue and used it on a rental property I helped renovate - it worked very well for a retrofit application but would be far too labor intensive for a new install. Also QuietRock has damping glue as well and it is 33% cheaper and has very good damping characteristics which according to "independent lab results" outperforms Green Glue. I am also being quoted $70 dollars for the Quietrock 527 series in 4x8 sheet.

I'm creating a room in my basement that will be approximately 12 x 12 x 7.5 I know it will never be acoustically perfect but my dream room will have to come later. I'm more concerned with it being quiet and isolated from the rest of the house. I'm shooting for an STC of 55 to 60+ with the weak point being the lack of a soundrated door which will have to come later.

Heat is forced hot water and the AC hasn't made it's way down from the main floor yet and could end up being a window unit. Noise traveling to the outside of the house is OK as my neihbors are not close.

There is no outside noise to contend with so I am most concerned with keeping noise from traveling to the rest of the house.

Where are the clips shown above available for purchase? I assume these would isolate the hat channel from the joist? Any damping compound between the two?

Ugh. Square rooms are acoustically awful. That's a shame.

I'm gone for ten days and your building a "quiet" room. 

Just untie the girl and let her go.....

He never did answer the question as to how many people were going to be in the room.

Sounds like you've used that one before........

I'll bring my leather catalogue over.

How quiet? Is there a lot of outside noise that you have to block? Any exterior walls? Any windows or doors to the outside?

Are you engineering this room (will there be math involved) or are you just trying to get the room reasonably quiet.

Is the listening room for primarily one chair (a "sweet spot" in the room) or do you want the whole room to sound good?

mookie is right, HVAC can ruin a nice quiet room. How is the room conditioned and do you have the opportunity to up size the ducts?

I can give you some quick and cheap tips if you answer these questions.

I tried answering those questions in my post above so not sure what else you need but appreciate the help!
