New interior walls - insulation

[Allez98]

I am going to put up two walls which will turn one large bedroom into two. I'm considering insulation mainly for sound. What is recommended? These are two bedrooms that will have long sides against each other, and the best possible sound insulation is desirable since we have small children in the house who should not disturb other children.
Is mineral wool the best sound insulation? Is 13mm plasterboard sufficient or is something else recommended?

Thanks in advance!

I will be putting up two walls which will turn a large bedroom into two. I'm considering insulation mainly for sound. What is recommended? These are two bedrooms that will have long sides facing each other, and as good sound insulation as possible is desirable since we have small children in the house who shouldn't disturb other children. Is stone wool the best insulation for sound? Is 13mm gypsum board enough, or is something else recommended?

Thanks in advance!

wood fiber boards, double gypsum board on both sides, seal around all joints. That's soundproofing for dummies. Then you can make it as advanced as you want after that.

If you mean it as well as possible, I think you should build a double stud wall with staggered, offset studs. It takes up slightly more space than a single wall, but it's not too bad. Mineral wool in between, OSB+gypsum on the outside, and carefully seal all openings.

I insulated and it works well, but one should remember that the doors are not insulated, so you shouldn't fool yourself into thinking it works exactly as intended anyway
