Soundproofing for apartment

[Chad Lundquist]

Dear BP Family,

My wife and I added an apartment in the basement of our residence and have been renting it out for the past year and a half with great luck, but the one complaint we get is the noise from the main floor. When I rehabbed the basement I tore out the existing drywall ceiling and added sound-proofing insulation followed by a 5/8" fire-rated drywall thinking that would be enough, but apparently the tenants can hear us walking, the dogs claws (we have hardwoods) as well as the TV. I'm not sure what else to do, but we have a month before the new tenant moves in and we'd like to get something done that is cost effective (not tearing out the ceiling again :). I've looked into soundproofing matting to attach to the ceiling, then the Z channels and another layer of drywall, but I wondered if anyone else has dealt with this. I'm open to any and all suggestions.

Thanks in advance for the help,

Chad
