Good evening,
has anyone had experience with how wall thickness affects sound transmission?
Currently, the shower is planned directly adjacent to the wall of the children's room. In the children's room, a wardrobe is planned along the wall facing the bathroom (a desk is drawn here for now; the children's room window will be moved so the wardrobe fits against the wall). At the moment, a 17.5cm (7 inch) thick masonry wall is planned. If a 10cm (4 inch) masonry wall would be sufficient without making the children's room too noisy, we could reallocate those 7.5cm (3 inch) to increase the shower size. Any experiences?

And then you have no mix of materials? In addition, lightweight partition walls are the worst choice for sound insulation – even when double-layered...That is and remains objectively incorrect. Drywall, when properly installed, is ideal for internal sound insulation and preferable to calcium silicate blocks. Your bad experiences don’t really disprove that.

Sebastian7930 Oct 2015 09:20OK, you win – I really underestimated the acoustic aspect, and our very negative experiences probably didn't help. Although the drywall partition towards the elevator shaft really didn’t let any sound through...

I would like to support Sebastian here. According to various sources, sound insulation is related to mass. By that logic, I would say a lightweight partition wall has less mass.
Mass alone is not the only factor, and clearly you have not studied soundproofing properly. The sound reduction index of drywall partitions (excluding standard basic types) is significantly higher than that of masonry. On Knauf.de, you can download PDFs showing what is possible and be amazed.
