I would use Auralex "U-Boats" or the eqivalent to float the  joists
directly on the existing floor.  Then make a composite floor:  
First a layer of 3/4" plywood, then a couple layers of 5/8" sheetrock,
being sure to have no seams lining up.  You can alternate sheetrock
and plywood for several layers depending upon your ceiling height and
your budget.  Sand is messy and not particularly effective. Add a
layer of Vinyl akin to "Sheetblock" under your last plywood layer.
Also.....be sure to thoroughly stuff the spaces between the floor
joists with insulation prior to adding your first horizontal layer.
This will take care of your sound problems.  Any layering below the
U-Boats will be either messy or superfluous or both.
