ᐅ Are prefabricated houses generally prone to sound transmission?

We visited the model home park in Fellbach near Stuttgart, and I am very disappointed with the interior walls.

All the prefabricated houses we looked at had hollow-sounding walls (knock test), and in most of them, you could easily hear people in the neighboring room or even conduct a simple test yourself. It almost felt like the walls were made of drywall panels.
I definitely cannot imagine living in a house like that. Just a phone call from the daughter late at night in the kids' room is enough to get annoyed. And I don’t even want to think about the noise from late-night activities in the parents’ bedroom...

Are prefabricated houses generally that poorly soundproofed inside? That can’t be the standard!?

Aerated concrete is not really known for good sound insulation

Multi-layered - and partition walls between units are always constructed this way - the "heavy" Ytong blocks perform reasonably well. But otherwise, sound insulation with Ytong tends to be rather poor in comparison.

If this has already been perceived that way, then only calcium silicate brick interior walls are possible. However, be careful, these also need to be decoupled from the formwork.
