This video (from Quiet Solutions) shows one way to soundproof a ceiling. This involves removing the drywall that's already on the ceiling in a downstairs room and replacing it with soundboard, a resilient channel (to keep the new drywall from touching the ceiling joists), and a layer of soundproof QuietRock drywall.
I can't vouch for the soundboard he recommends in the video, especially because he mentions that there's wood in it (and wood is typically a sound transmitter), and I wonder if a layer of Homasote 440 would be more effective, but you get the idea: fill the hollow areas with insulation, separate the joists from the ceiling below, and use a sound absorbing material on the joists themselves.
My downstairs neighbor had something done on his ceiling below mine, but it was slightly more complicated in terms of labor, and a lot more expensive than this solution. Take a look....it shows you the basic concepts of how to keep sound from going upwards. Of course, you'd have to get cooperation from a downstairs neighbor to do it....
