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?

Make it at least 17.5cm (7 inches). Even that thickness seems borderline to me. We have a 17.5cm (7 inches) Poroton wall, and you can hear everything from the other room. We are considering adding a drywall partition in front of the children’s room walls during the next renovation because it is really very noisy. Fortunately, the shower is on the bedroom side, and you can hear every drop. On the children’s room side, we have the washbasins, which is more manageable.

There is a good reason why some suppliers offer non-load-bearing interior walls above the ground floor in lightweight construction. This also avoids issues with mixing materials.Best regards, Bauexperte

We use calcium silicate blocks everywhere to achieve consistent settlement behavior. Moreover, the soundproofing is better, and we install appropriate doors for this purpose. Still, those remain the weak points...

In addition, lightweight partition walls are the worst choice acoustically – even when double-layered. According to whom?

We have calcium silicate bricks everywhere to ensure uniform settlement behavior. Furthermore, the sound insulation is higher, and corresponding doors are installed here. Nevertheless, these remain the weak point... You are convinced of what you have built/had built; that’s good ... for you! But that doesn’t mean that calcium silicate bricks are the best solution for everyone.

Sebastian7929 Oct 2015 09:51I’m not saying that either – but acoustically, it’s definitely the best solution among all the wall constructions described here – or would you disagree?
Regarding lightweight walls: I’m speaking from experience, not just reading about it. We had a double-layered, DOUBLE lightweight partition wall separating the living room from the neighboring apartment. One floor above was a regular sand-lime brick wall – and the difference was clearly audible. Unfortunately, that was a major annoyance, so I definitely wouldn’t install something like that in my house...
