ᐅ Prefabricated home builders with good sound insulation?

I believe the issue lies with the bypass opening of the controlled residential ventilation system. The wall construction consists of 14mm (0.55 inch) gypsum board on both sides, with a 14mm (0.55 inch) chipboard layer in between, surrounded by mineral wool insulation.
It’s still manageable for now, but if my girls have guests over, oh dear...

Acoustic engineering is an overall concept

Yes, that’s clear, which is why I’m asking here.

It’s not only what’s on the wall that matters, but also what’s inside it ;-)

I see. Well then... thanks.

The misconception that prefabricated “ready-made” houses are inherently inferior in terms of sound insulation exists only in people’s minds, nowhere else. If that applies to your mind as well, the only solution “helping” is to build solidly—by forum consensus, sand-lime brick is considered the top soundproofing material.

I’m aware that a prefabricated house can even have better sound insulation because the walls are boarded on both sides. But still, that doesn’t have to be the case. Almost every prefab manufacturer has a different wall construction, so it’s hard for me to judge, which is why I’m asking for experiences.

I play electric guitar and would like to be able to sometimes play loudly without disturbing the neighbors.

The marketing material from Schwörerhaus seems the most convincing to me, for example that the roller shutter box can also be additionally soundproofed, just like the windows.

But as I said, I prefer real experiences, especially from someone who also likes to play electric guitar a bit louder, possibly drums, piano, saxophone, etc.

I think it’s due to the overflow vent of the controlled residential ventilation system...

Yes, that also makes me think... controlled residential ventilation, roller shutter box, window.

In hindsight, I probably should have asked differently, since this is more about a "music room."

Due to the location of our building plot, we also have to meet various sound insulation requirements, so we opted for soundproof windows facing the outside and the aforementioned insulated roller shutter boxes. We have no concerns about noise from the outside. The neighbors with solid houses had to invest more in this regard.

When it comes to this, I believe Schwörerhaus is a reliable choice. I would also consider paying more attention to sound insulation inside the house.

... I consider this a "causality" on the level of a "baker’s flower" (meaning a false correlation). While boarding is not used exclusively, it is predominantly applied to stud walls.

"The marketing material seems convincing" is a comment on Schwörerhaus that I could not have phrased better myself 🙂

Yes. And you should not choose the supplier based on all interior walls in the house, but rather customize this one room with special equipment. When your concern is refocused this way, I see your question as similar to that of @Paulus16, see here: https://www.hausbau-forum.de/threads/innenwaende-porenbeton-kalksandstein-oder-leichtbauwaende.25259/#post-219289

Ok, unfortunately I can’t follow 🙂

Sound insulation is important to me for the music room, but not only that, also overall.

I’m also considering building with a basement, then a room-within-a-room. But that gets very expensive.

Can’t follow again... 🙂 It is marketing material, but I still think it should be evaluated positively.
