The eternal question - how to soundproof between rooms...
(forgot the question mark in the title)
I have opened one side of a wall as I wanted to soundproof it (within reasonable limits).
I had planned to open one side, seal the back of the existing boards on the other side, then pack in a lot of mineral wool, and apply new boards. Then seal all the joints obsessively.
But then I read a bit... Some even suggested that this can cause more noise, so now I'm a bit conflicted.
1. I'm not planning to increase the thickness of the walls...
2. Today, all are uninsulated.
3. The goal of this wall is to isolate human and TV noises as much as possible.
Since one of my cameras is broken and the other is missing without a trace
I had to draw how the frame looks in this particular wall between the living room and one of the bedrooms & WC.
**discovered a drawing error, the overlaying board does not touch the frames but is 2-3cm above them**
On one side, there is about 10mm of masonite which I plan to keep. On the other side, I plan to be generous with 13mm drywall. - Some say that it's good to mix different materials to capture different waves... but whether this mix is effective, I don't know...
* But in the texts I've read, people mention OSB boards, whatever they are?
* And people talk about air gaps - how am I supposed to achieve that with 8cm depth?
-------------------------
Another wall I've opened is between the living room and the stairs... There will likely be some thumping noises when people run up and down the stairs... Should I use a different insulation method there?
-------------------------
The third wall I've opened is between the bedroom and the exterior wall/garage - I assume I should use other insulation that is as warming as possible?
-------------------------
When dealing with interior walls, should one use plastic? With fiberglass, then plastic, then boards... or is that unnecessary? The angry handyman always scolds people about how bad it is for health with insulation, so I got a bit hesitant, but with boards and wallpaper, nothing should be flying out, hehe.

just put in regular 70 insulation and drywall.
Even better soundproofing with ground board and even more with double drywall.
You can put an OSB board before the drywall to have a good wall to attach things to, instead of anchoring everything in the drywall.

You can increase the wall thickness by 1 or 2 cm so you can insert studs of the same dimension as the existing ones, but shifted 1-2cm "in depth" on the wall. This means that the plasterboards on each side of the wall will be separated, i.e., no continuous studs. This dampens structural noise. Fill the leftover space with insulation wool completely or partially. Check out Isover's website: http://www.isover.se/byggkonstrukti...er/mellanväggar/i-c3-213+träregelstomme+55+db
