Chipboard 12mm and 13mm gypsum on interior wall, is it enough?
One is never ceased to be amazed by people's overestimation of insulation in walls regarding soundproofing capabilities...
What soundproofs is density, mass, and distance. It doesn’t get simpler than that... Insulation absorbs sound mostly, not isolates it... There is a significant difference...
2 plasterboards of 13 mm each are more effective than 2 m of insulation...
Stop overestimating the soundproofing capability of insulation.

Mrz .. that was a strange attack I must say. It was probably more a discussion about what is best in terms of insulation (damping). In other words, different materials dampen in different ways, so it was more a creative attempt to get advice if there's something other than isover insulation to use, among other things.
One thing is the sound in the room itself, the other is the sound if you knock a little on the wall... making it sound hollow and tinny (though it should be easy to screw things up). I think we're looking for a solution to both things as best as we can.
So why get so upset about this... feel free to share something constructive instead... that would be nicer.

I've heard that sawdust is supposed to insulate sound better than glass/mineral wool.
It aligns with Mr. Z's line of thinking that heavier materials dampen better.
Sawdust is probably quite cheap too, but troublesome to work with—how do you fill a wall with sawdust, for example?

Hmmm, I wouldn't want sawdust in my walls considering the fire risk....
By the way, I have OSB + drywall + insulation (70-125 mm) and together with really solid interior doors with rubber seals, I think it soundproofs really well!

I apologize if I went a bit overboard with my last post... I blame it on having a bad day... :
Sawdust is not directly soundproofing either... Wood is generally quite useless overall as it has a tricky density and so on...
And sure, insulation helps to increase the overall soundproofing, but not as much as you might think. 1/3 of the space needs to be insulated to achieve maximum effect. At the same time, one shouldn't underestimate the "experience" either.
Concrete is by far the best if we are talking building materials, or alternatively, bricks are excellent. Now, this might not be an easy task to fit in a mold to cast an interior wall in a housing directly, which is why one opts for the next best, gypsum, which is both cheap and a relatively good wall material from many perspectives.
Furthermore, it's not just the wall that determines but also the reverberation time and many such things cause trouble. This is something that in 99 cases out of a hundred you don't even need to consider unless you're going to build a room specifically for sound, like a home theater or studio, or maybe even a little Hi-fi enthusiast corner where you can enjoy an old record or two
Many choose to use OSB, chipboard, plywood, or raw paneling to more easily mount furniture and the like on their walls. This is a choice made as the soundproofing ability of the wall becomes worse but the practical use of the wall increases, which is often the guiding parameter. (next after price and the partition itself)
But to return to the insulation in the wall as such. It absorbs the internal resonances in the box you have and really nothing else. Granted, you can cram in foundation slabs or other heavy insulation in the wall to increase the total weight, but I consider it completely pointless to take this approach, especially in single-family homes, as it is significantly cheaper and particularly simpler to equip the wall with 3 layers of gypsum and achieve the same result. The foundation slab can be applied in premises with higher sound loads than the internal sounds created with speech and appliances... With the exception of stereo and other loudspeaker-based sound-producing items...
Many can today, however, have problems with subwoofers and the like in the age of home theaters. This is resolved with room acoustic measures, and here insulation is particularly effective... Imagine a PET bottle; it has a resonance frequency around 200 Hz somewhere, i.e., about an octave lower than the sound you hear when you pick up the phone... It functions like an organ pipe... if you fill this with insulation, it absorbs a certain amount of sound in the 200 Hz range... no, I'll stop now because this could become an essay that just becomes long and generally rambling...
But I hope I've clarified something at least...
