Sound Proofing a 2 Channel stereo system
« on: July 03, 2014, 08:02:44 PM »
This will be a new build in the basement, about 12'X16', Every where I have read it says to use double dry wall, but that will be  cost prohibitive, so looking for some sense compromises.

1, Two wall will be against the foundation, the non foundation walls will have staggered  studs, and I thought about using MLV in those walls as well as insulation. The other two walls will be insulated as well, If using the MLV do you need to staggered the wall studs? Should the wall along the foundation also be staggeared? Should MLV be used on all walls?
2, Use MLV on the ceiling with a "HAT " system, to reduce sound transfer to the up stairs.
3. All dry wall will be 5/8"

The goal is to have a tight room without going overboard, mainly need to limit the sound transfer to the upstairs. The MLV Will be 1/2 lb weight.

Thanks

You think double drywall is 'cost prohibitive' but you have no problems using MLV?  Are you high?

Not high. . . Thanks for your concern.

Looking for suggestion and recommendations other than double dry wall to do sound control.

Ok, let me jump in here on this one, when it comes to quality sound control you can not get around the physics.
In order to achieve a cost effect solution you must decouple from the structure ie. double framing or clip and channel.
And you MUST add Mass! lots of it !
The difference between materials used in the industry really comes down to a few factors,
lbs. per sqft or density.
thickness of material
and finally cost.
depending on weather or not you have the space to add thick walls then you can achieve this pretty cheap but if you dont have the space that is where thinner but denser materials come into play.

And finally the most important part is to build the system based on the noise source properties and desired reduction... I can not tell you how many times I see people soundproof with minimal mass and think they are going to get good results only to be disappointed...if your going to invest in such a project do it right the first time!

Soundproofing will never be "Cheap" if you want it to work, but there are ways to get bang for buck!

In your application, one additional sheet of 5/8 drywall will be acoustically equivalent to 4 layers of .5 pound MLV.  Do the math...
