caliberger,
These tables give you a good idea as to how various wall assemblies will perform.

Most sound transmission is through air, so the first step is making the rooms as nearly airtight as possible.
That probably means each room has its own HVAC registers and returns, with sound attenuation. I wouldn’t bother with insulating the walls until that’s done.
