Sound reduction with insulation

We have main level room that sits above the basement utility room which houses the furnaces, water heater, and lift pump. The ceilings in the utility room are exposed. Several pipes/duct work run through the expose floor joists as well. We are trying to prevent sount from this room being heard in the main level bedroom above it.

Would insulation in the utility room ceiling help this?

Insulation inside the floor joist cavities will help a bit, but to work very well you need to uncouple the floor joists and drywall.

any way to get heavy pads on the floor above, like dense pads under the carpet (if you have carpet)? sound deadening sheet rock on the ceiling should help, too.

if you can, build a separate ceiling below the joists. fill the voids with mineral wool, then drywall.
