Hi,

If anyone has succesfully managed to soundproof a ceiling from the noise
from the upstairs flat, I'd be glad to hear from them.
I am thinking of doing same and would welcome any helpful pointers.
Thanks

I tried to do this and had some success.
You have to think about it in different frequencies.
Low frequency noise i.e. upto 1kHZ is difficult to get rid of. This mainly
consists of things like heavy footed people, general thuds etc. 1Khz to 4Khz
is about 80% of all voices this is quite easy to get some initial results
but hard to eliminate all together. The higher stuff above 4 Khz to 40Khz is
easier still.
You also have to consider the type of noise, i.e. Impact or constant
emission. The constant emission is quite easy to reduce.

Firstly check to see it you have any noise paths between you and the other
flat(s). Hot air ducting is a common one as is wiring/pipe voids. Where
possible you can filter this noise with good thick insulation or expanding
foam. (not so easy in heating ducts).
Things like installing draught excluders helps, especially the air tight
ones (As sound is transmitted be the transference of the compression of air)
Next your ceiling and floor. The floor is easiest. Fill it full of loft
insulation (taking care of the building regs). The ceiling: You could use
anything from thick wall paper, polystrerene tiles to fitting a false
ceiling void and filling that also with insulation.

If you read any books on noise, it will tell you to reduce the noise at
source first!

Hope this helps.

Regards

depends how far you want to go, but the latest and best way is to use things 
called resilient bars.  you screw these metal bars (cost about 4 each for 
2.4 mtr lengths) to the existing celing joists, and then screw a double 
layer of plaster  plaster board to these bars, creating a new ceiling that 
is not screwed directly to the ceiling joists.  You could also put some 
rubber matting underneath the upstairs carpet if this is practical. 
Whichever way you go, to be effective is going to be costly.
