Sound my friends, sound!!!! One layer = ridiculous, double layers = ok... Some insulation will reduce it further... But my advice for interior walls is minimum 70mm studs and 2 layers of plasterboard or 1 layer of plasterboard and 1 layer of OSB/ply or even rough cladding, but only on wood studs.. Personally, I prefer metal studs, they are better on almost every level...

???I personally hate metal studs! I think they are a nuisance to work with. Wood feels sturdy and stable, is easy to work with, and can be built into the most fantastic angles and configurations (for those who care!). Metal studs get their strength from the rest of the wall construction... that is to say, the sheet material. Oh, one more thing... it smells so good when you saw dry and fine wood! ;D
Regarding gypsum, it might depend on what kind of wall it is. If it's between bedrooms, definitely use double gypsum/gypsum+råspont/OSB, but if it's just other types of partition walls... between living room and dining room, hall and toilet, etc., you might cut back a little.
I would probably say that the toilet is nice to soundproof... And the kitchen.. A lot of background noise comes from the kitchen.
And Gromit, metal studs that can be shaped so well, and the idea that it would be easier to build with wood, I don't buy. It's no coincidence that 90% of all walls in construction consist of metal studs, right? It's faster, slightly better sound reduction, at least as shapeable as wood offers, lighter constructions, makes it easier to insulate, etc...
Wood has an advantage since it is more stable, so for load-bearing structures, it's better. However, there are reinforcing studs in metal which can be a real h.......e to work with in some cases. But if I use wood, in 99 cases out of a hundred, I have metal as a supplement, making the whole process easier and saving time, and time is money, and messing with others' time is like messing with others' money
