is it actually irrelevant for soundproofing what material the house is made of? Because usually, the standard window with less than 40 dB is almost always weaker than the wall itself.
Does a good dB value for a specific wall construction even provide any benefit?

I’m not entirely sure what your question is aiming at. Is it about requirements for sound insulation? The calculation involves a mix of the insulation values of walls, windows, roof, etc. How practical it is when the individual elements provide very different levels of soundproofing is another matter. We even manage the trick of having the windows block more sound than the walls. 🙂

mikiliki12328 Nov 2016 23:38I have to decide between a solid wood wall and a Ytong construction.
The timber builder says the wall can achieve 56 dB sound insulation.
Ytong only 42 dB.
The other builder argues that 56 dB doesn’t matter if the windows provide less than 40 dB.
Sound insulation is important to us.
This is just one aspect of our decision.
I just wanted to know who is right.
Both statements sound plausible 🙂

I believe that’s mostly correct. We have exterior walls made of sand-lime brick and windows without any specific soundproofing requirements – I think that’s about 36 dB (decibels) (?). In any case, the sound insulation by the large windows is rather disappointing. Fortunately, this isn’t a major issue because we live in a very quiet area.
That’s what I meant about the mix between calculation and practical application. We also have Ytong with 41 dB. If you combine it with external thermal insulation composite systems (ETICS) / external wall insulation, it can either worsen or improve the value, depending on the type.
What wood can do, no idea...
36 dB is probably typical triple glazing with three 4 mm (0.16 inch) thick panes. 49 dB is possible – that's what we achieve. Of course, there is also quadruple and quintuple glazing, but those are more common in hotels with specific requirements than in private residential construction.

I would love that too. But isn’t that unaffordable? 🙂
