I've bought some regular rock and hat channel, and still need to get the green glue and soud deadening clips needed to install double layer 5/8 sandwiched with Greenglue in the joist cavities of the ceiling, followed by hat channel on clips and a rocked, celing. Possibly with sound deadening rock.
I'm worried still though that even though this is supposed to be great sound proofing that it might not be able to give me peace. Is there is anything in particular about old houses that can negate all this work? My main concern is the squeeking an creeking hardwoods and the foot fall traffice that results in major "bass" coming down into my space. Assmuming I can re-route vents and apply the rock in the joists, with green glue and then the suspended ceiling, can I expect to have almost no issue with normal foot issues, or will I get reverbirations from the upper hardwooks, down the joists, into the top plate and down the studs into my level?
Thanks for you help,
