Sound proofing floor

I am at the point that I don't need to modify or purchase anything else. But I am considering sound proofing the floor for the sake of my neighbors which know that I will lower the volume when they ask. I am considering raising the floor and making that raised floor decoupled from the room and insulated.
Any ideas?

The biggest transmission of noise is air leaks, so the suggestion to caulk is a good one.

If you're ready yo go through all the trouble to raise the floor, how about pulling up yout subfloor and filling below it with expanding foam insulation? This should really seal them off from your floor.
