If you do a TF to reduce noise we did the following:
Every internal wall put in min rockwool, my sisters house (built on estate has none! )
Ceiling space, put in either rockwool or fibreglass, for both heat retention and noise reduction.
Main rooms ie sitting room, dining room, kitchn - sheet with ply to again reduce noise.
If you can may pour a light screed, upstairs we put in UFH. Under it we had the 25mm of insulation which was between 50mm batten. The UFH was attached to this, then the screed poured to the top of the battens.
With all of the above we have no issues with noise, yes it is not 100% but it is much better than most "production line" TF houses.
