I'm going all out full bore on a project but worried now that I may have to do something with creaking hardwoods on the upper floor. Can I finish this install (2 layer sof green glue below the subfloor down stairs and a decoupled, clip and channel ceiling downstairs and deal with screwing the boards into each joist up stairs later on? I'd contemplated screwing a 1/2 plywood layer right on the sub floor with some tough PL construction adhesvie to bond the whole thing but, the layers and just piling up and I'd rather not have a plywood layer, and two rock layers in every single cavity.

Opinions on this?

just adding layers will not stop the initial problem. you must resolve that problem before continuing forward.

Anything that can be done from below? Will putting some screws up through the sub floor and into the hardwoods do much to tie things together and lessen the issue?
I guess the big question is, if the only solution is to screw down from above, can I proceed with my plan to add layers (drywall and green glue) to the underside and address the securing of the hardwoods planks to the joists in the near future?

I'm wondering how you got on?

I've had a nightmare with squeaky floorboards from the apartment above - just enough noise to wake me when they go to bed late early mornings.

I'm looking at a soundproofing the ceiling and Green Glue would be the easiest solution it seems. I have bay windows that go to the ceiling so need to not lose much height. However, does it really work? I hear it's good for airborne noise but what about impact and the 'squeaks'?

The alternative is Acoustic Hangers (http://www.soundstop.co.uk/solutions/ceiling_access/ceiling_solution_2.php) solution. I can't seem to get a definitive answer as to whether this would be more effective or not. The last thing I want to do is to have to do it all over again if one or other is not effective enough.

Any help greatly appreciated.

Ok Guys.... Squeaky floors are usually because nails have backed their way out of the joist and floor boards (if glued also then the bead has broke) and now every time someone walks on them the board is free to move... if you able to toe nail from below that might reduce some movement but the correct solution is to put in screws from above...

When dealing with impact noise it is a 2 part solution:
1) decouple the path from the new drywall ceiling to the joist ( ie clips and channel)
2) you must control the cavity with MLV and add absorption in the cavity(cotton fiber or mineral wool).
just by decoupling alone only addresses the direct connection.....you are then left with the BOOM sound generated from above.....
Your max value would be 50% reduction of impact noise....if you think you will achieve a greater reduction it most likely will not happen due to the flank value of walls.
The only way to increase this value is to reduce the impact at the source....not the receiving side.
