There are are a number of solutions on the market I've been researching for soundproofing a ceiling due to noise from neighbouring flats above (both airborne & impact noise).
In my case, it's a Victorian property divided into flats. Joists are deep (8x2) and existing lath & plaster ceiling removed. Floor above is timber floorboards and some cr*p carpet (no underlay) or equally cr*p vinyl effect laminate stuck to 9mm ply over floorboards. These are separate flats so no chance of insulating from above unfortunately. No possibility to drop ceiling much due to window height either.
Current plan is 100mm Rockwool RW3 between the joists (for airborne noise) and one of the following for impact noise:
Oscar ISO Mount
Expensive & more difficult to install than the rest but best for minimal ceiling loss height & uses standard GL1 metal channel.

Genie Clip
Similar to ISO Mount in design but even more expensive & uses proprietary furring channel

ISOMax Clips
Rubber mount for proprietary metal channel that screws to bottom of joists. Cheaper than solutions above but more loss of ceiling height.

Resilient Bar
Widely available and cheaper than the rest but potentially worse acoustic performance & would require 2 layers of 12.5mm Soundbloc plasterboard to achieve a decent result.
There are also various rubber membranes available which stick between layers of plasterboard but no real idea if these work or not.
Anyone any feedback on using any of the above systems and what the results are like?
