soundproofing bar below apartments
« on: March 01, 2005, 04:38:43 AM »
We are opening a bar that is below 3 apartments. we hired a "sound guy" that my brother knows and he garaunteed that the job he would do would prevent any sound from reaching the tenants in their apartments.  He proceeded to install between the 2"x12" joists R30 insulation below that he added 2 sheets celotex and 1 sheet homosote. Is this suffient to create the nessecary STC  needed for a  bar? And if not can anyone please make a suggestion.

Doubtful this will achieve the level of soundproofing you'll need.  See
for the options of using different materials and techniques to get to the higher levels of soundproofing.
