In Reply to: Interior Wall Sound Control (Urgent) posted by Saji on February 17, 2001 at 18:36:40:
While it is difficult to build a truly soundproof wall, you can construct a second wall using 2x4 framing (sill, header and studs) and leave a 1" gap between the existing and new wall. Because these are interior walls, use unfaced insulation as there is no need for a vapor barrier. You will need to move electric outlets and ceiling fixtures from the old wall and ceiling to the new wall and ceiling. When you attach the new drywall to the interior, seal it up as much as possible with paneling adhesive. This may not be perfect, but should help significantly.
