Think in terms of isolation, not insolation for room to room noise reduction.

The door is probably a huge 'leak'. AIr seal all around the frame ofthe door, using weather stripping type materials: foam, rubber strips, ALL AROUND the door.

If you literally seal the door crack all the way around, this will provide a huge improvement.

Unfortunately, after this relatively easy step, things get a LOT harder to get further improvements.

If the option is there, you might want to consider some of that expanding insulating foam in a aerosol can, which only needs a small hole to inject it into the hollow center of the wall between the two rooms. This would be the next best improvement.

You would have to do every hollow isolated section of the wall (look at how most walls are constructed, with vertical frame members, and crossbraces on every vertical member), and be careful not to make a mess by having a plastic dropcloth in place if the foam starting dripping from the hole OR oozing out from cracks or crevices. These types of foams ususally recommend a wet cloth to wipe up such spills IMMEDIATELY, so you may need a partner to help keep the mess down to a managable level. The foam also stinks, and might need to have ventilation for a day or two. Be sure to thoroughly read the warnings and instructions on the can BEFORE you purchase a dozen cans to do the wall, and decide if you really want to do this!

I would try doing up the door to the max first, and see if this helps enough.
