you mean that simple gypsum and studs are enough?
the best thing about having two layers is you replace one sheet with plywood

Consider how good sound insulation you want and choose the door and wall construction accordingly. Soundproof doors are significantly more expensive than regular interior doors. An advantage of choosing thicker walls from the start is that the doors can easily be replaced over time.
Due to space reasons, the walls can't be as thick as would be optimal for sound.
We are building a small villa with small rooms. But of course, we want to make it as good as possible given the conditions.
We have prioritized OSB/Plywood instead of double gypsum to be able to attach shelves, etc. The walls are 45x2 crossed (70 total), 2xosb11, 2xgypsumx13mm = 118mm total.
A solution that might improve sound is to replace OSB with gypsum and screw horizontal studs into the walls to hang things from.
A 35db door seems to cost around 3000kr, by the way.

skip OSB if you want good grip in the wall.
no, it won't be cheaper if you have sound requirements

What is the sound that needs to be dampened?
Budget?

It's not really possible to say, but the thread began with the idea that the door is the weak point in the whole system, and is there any point in, for example, making a wall with all possible sound solutions that can handle 50dB when the door measures at 20dB?

There are plenty of interior doors to choose from, you should have a solid door with a rebate threshold. The question is just how much money you want to spend. Dooria is among the most affordable.

Of course, the construction is only as good as its weakest link. As you said, it's pointless to have a sturdy wall if there's a centimeter gap at the threshold.
If you choose a wall construction classified as 50 dB R´w, it implies values measured in a lab environment. In reality, one can expect slightly worse results. However, the wall is usually built more robustly than the door. For example, if you choose a 35dB door, it's appropriate to have a 45 dB wall. There are, of course, doors with higher sound ratings, but they come at a higher cost.
You'll simply have to consider whether you think the cost is justified. If you look at Fermacell walls that are around 50 dB, they are not particularly advanced constructions. There's also the option to dampen sound with absorbers in the rooms. Ceiling absorbers, wall absorbers, thick carpets/curtains, etc. It all depends on how much you dislike noise and how thick your wallet is.
