In the picture, the dark joists are how I have it today.
The question is whether I should place double light ones between the old ones... or
put a light one against the old ones...
In my theory, it would be better with more joists between the old ones... more evenly distributed instead of few and stronger... should make the plasterboards vibrate less... and should stabilize the upper floor better...
But on the other hand, I would have to shred the insulation more if I do that, and I'm not sure what effect that will have?

Hello!
Are you planning to soundproof between the rooms on the ground floor and stabilize the upper floor?
If I understand you correctly, I would suggest staggering the studs and attaching the panels only to one side of the studs. The two halves of the wall should not be connected. Fill up with insulation between the studs and perhaps use double layers of plasterboard (the more mass, the better). If you have a door in that wall, a lot of the sound can also come through there.
Hope you understand what I mean.

Yes, I have read a bit about staggered studs, preferably so it becomes a bit of a zigzag, and the explanations for this, although I'm a bit skeptical, but sure, it can be done. But I'm not planning to add more gypsum, etc., just doing what can be done based on existing measurements.
But this thing with double gypsum, in other words, the stiffer the better, in other words, the best would be if the entire wall was one single stud, then nothing can vibrate, yes, that's my logical thinking that no one wants to acknowledge...
But as mentioned, I could have gone with staggered studs...
Is there any disadvantage if the CC distance is smaller?
And if one is to think extremely, if you have staggered studs, it means they are not as deep as those that already exist... not as deep, then they don’t cover the entire wood panel on the ceiling and floor, so it’s probably off-balance, and likely to creak and whatnot?

Installing noggings between the studs stiffens a lot.
If you want the wall to become stiff, you can glue the board (chipboard) for example and screw it, then screw drywall onto the chipboard; that will make a difference.
