Best option for a partition between control room and cabin

Hello,
A year ago, I converted a part of my house into a studio by dividing it in two. Since the part that was already converted is becoming too small for my needs, I'm going to convert the rest of the room (on the other side of a partition) into a cabin.

I would like to know what the best option would be to ensure the two rooms are as well insulated from each other as possible.

In the attached diagram, I'd like to know if the yellow area between the two partitions should be left empty to create a box within a box, or if, on the contrary, it should be insulated with wood wool, rock wool, or something else to block out the sound.

Note that the red line is the current door between the two rooms, and the green line is a window between the two rooms that would be installed during the partition work, with a double-glazed window system on each side of the partition.

Thanks in advance.

I suppose much depends on what the walls of the studio - not the partition - are made of. Isolation comes from mass and a gap. No point at all in over engineering the partition between two spaces, if the sound can leak out and back in through a poor external wall? Assuming the existing space works well enough, sound transmission wise, to keep inside sound in, and outside sound out, then my own studio building history says build two walls - each one with a double glazed window and proper door - faced with sheet material on the room sides and filled with rockwool in the cavity between them. My current home studio was set up like that, but I actually removed it to go back to one big spaces when I stopped having people in, and just recording myself in the main. My own system is two layers of plasterboard and then one layer of MDF - because it's very solid and heavy and you can screw to it, decorate it easily and the surface resists crashing flight cases into it.
