I am going to build an interior wall on the upper floor and would like it to be soundproofed. I have looked around a bit and got some tips, but some questions remain.

I will have insulation between the plasterboards, and the wall will be built on an existing wooden floor.

1. Double plasterboards are recommended. Should this be on both sides of the wall, or is it overkill?

2. Sometimes chipboard is recommended inside the plasterboard to create better attachment options. If you do this, will it be as good soundproofing as with double plasterboards, or is it better to take double plasterboards instead of chipboard plus plasterboard?

3. In some places, I have read that you should seal the sill (floor rule) with some sealing compound, but in other places, I see recommendations to use sill insulation under the rule. Insulating the sill sounds simpler and better; does anyone have an opinion?

4. Since the wall will be placed on a fairly nice floor, I think that it would be good if someone in the future would want to remove the wall, it can be restored. It would require filling in screw holes and maybe sanding the floor, but it should still be possible. Any thoughts on this? Anything to consider during construction to make it easier?

5. Sealing against the ceiling should also be as important as against the floor, right?

6. There will be a door in the wall, and I assume it will let through the most noise. Door frames with integrated sealing strips are also something I've counted on. Any tips on soundproof doors and other considerations?

Grateful for all tips!
 
What sounds should the wall & door dampen?
What frequencies will the sound have?
How many dB do you want the wall & door to dampen?

How are the existing floors/walls/ceilings constructed?
How is the existing ventilation?
What will the new ventilation be like?
 
It's the teenage son who wants to be able to have friends in the room with some music and conversation later than the rest of the family desires. Also, the opportunity to sleep a little longer than the rest of the family sometimes, without being disturbed.

So I don't really know about decibels and stuff 😊

The ventilation is natural in a house built in 1972. We are about to move in and are now planning for some things we want to sort out. Ventilation is one of those things where we want better ventilation at a reasonable cost.
