restaurant sound issues
« on: October 24, 2007, 11:49:52 PM »
We are re-locating to a space with poor sound control.  We will have a neighbor on each side. Dividing walls are metal studs, 16 OC, with no insulation, 1/2 drywall.  I am concerned about disturbing the neighbors with our PA volumes.   We produce music volumes similar to a night club... actually, not as loud as a nightclub, but would any of the following scenarios be adequate in stopping nightclube volumes from going through walls?

- additional layer of 5/8 drywall with green glue
- blown in cellulose insulation and then additional layer of 5/8 with green glue
- 2 additional layers of 1/2 drywall with green glue
- blown in cellulose insulation and then additional layers of 1/2 with green glue

Will any of these scenarios be adequate?

Thanks
Scott

Your best bet of the options you list is the fourth one:
-blown in cellulose insulation with added layers of dry wall with Green Glue
However, you'll get best results with 5/8" thick dry wall (rather than 1/2") and use maximum Green Glue - 3 tubes per 4x8 sheet of dry wall.  It's true that multiple layers of dry wall with Green Glue works best.
You could consider of adding a layer of MLV w/PSA (pressure sensitive adhesive) directly to the existing wall's surfaces first (peel&stick) and then the Green Glue, dry wall, Green Glue, dry wall.  This will give added mass at initial surface.
