Does anyone have experience with insulation or lack thereof in interior walls when building a new single-story house? The walls have studs that are 45x70, 13 mm OSB, and 12 mm gypsum. Is it worth putting insulation in the walls considering soundproofing? Thanks in advance.
The biggest advantage of insulating the cavity is that you can have different temperatures on either side of the wall.
As airborne sound insulation (talking and music, for example), it is also an improvement, but not a perfect one. As impact sound insulation (footsteps, etc.), it's entirely ineffective. That requires a different wall construction.
Now, 7 cm MU doesn't cost a whole lot, so it's better to do it than skip it and then wish you had done it. It provides the benefit it can.

you gain roughly between 3 and 6 dB sound insulation with wool in the wall... More because you take care of internal resonance than actively soundproofing... But that's another story...Oj said:
You should think about 3 simple things
1) Tight construction
2) Double layer of boards on each side
3) Tight construction (again)
For example, a sawdust-filled wall probably dampens sound better due to the higher density of sawdust? Or am I also off riding a two or three-wheeler...zankan said:
Then it's as complex as a problem can get, it depends, among other things, on frequencies, etc...
I heard that in the newly built House of Music in Uppsala they have walls with like 9 layers of plasterboard or something, to sufficiently dampen between different salons.
In general, one can say that wood is more or less useless when it comes to soundproofing properties, due to its peculiar density... But sawdust is a different type as it, when used as filling, is supposed to do the same thing as wool... That is, not soundproof but absorb...
And if you're going to soundproof abnormally, you use a traditional plaster wall and, for example, a brick wall to create better reduction values, etc. I could sit and give a lecture for hours, but I have a job to manage
