I own a building which has a bar on the ground level. I have an apartment above and you can hear everything. Is there any type of spray soundproffing that I can spray on the ceiling?
While some sort of spray would help, it sounds like you'd want something a bit more than that. sprays deaden sound by reducing resonance. Assuming you don't have a sheet metal ceiling, you probably wont see a ton of improvement.
you might also want tot look into weather you are getting sound transmission through light fixtures or duct work before you just assume it is just through the floor/ceiling materials. Once those 2 are taken care of, I'd probably add insulation between the floors.after that, I add another sub-floor gapped up slightly and/or some of those loose wood shaving panels on the ceiling
An option, if you have the money and the building will support it, is to pour a 2" concrete (or gypcrete) floor. You can install radiant floor heat at the same time, if desired. That is a major revision, so think it through. If you can gut the interior and pour the whole second floor in 'crete, you ought to be pretty sound proof.
