I made a level 3 system in my home theater and it seems to work pretty well.
The other parts of the basement with just drywall attached directly to floor joists and insulation inside do practically nothing in comparison and footsteps can be heard from above/music and voices can be heard from below.
This company has a lot of great information about soundproofing ceilings on their website.
