Soundproofing - weakest link? (Windows?)

Hello,

is it actually irrelevant with regard to soundproofing what material the house is made of? Because usually the standard window with under 40 dB is almost always weaker than the wall itself.

Does a good dB value even benefit me with a certain wall construction?

I'm not entirely sure what your question is aimed at. Is it about requirements for sound insulation? A mix is calculated from the insulation values of the wall, window, roof, etc. How practical it is when the individual elements provide very different sound insulation is another question. We even manage the trick that the windows absorb more sound than the walls. :)

I have to choose between a solid wood wall and Ytong construction. The wood builder says the wall can handle 56 dB. Ytong only 42 dB. The other builder says 56 dB doesn’t make a difference anyway if the windows are less than 40 dB. Soundproofing is important to us. It’s just one aspect of our decision. I just wanted to know who is right. Both sound plausible :)

I think that's somewhat true.. we have KS exterior walls and windows without any soundproofing requirements - I believe that's 36 dB (?) .. .in any case, the soundproofing in front of the large windows is rather poor. Fortunately, that's not so dramatic because we live very quietly.

That's what I meant by the mix in calculation and practice. We also have Ytongg with 41 dB. If you combine it with [WDVS], it can worsen or improve the value, depending on the type.

What wood can do, no idea..

36 dB is probably normal triple glazing, 3x 4 mm thick panes. 49 dB are possible - we actually get that. But of course there are also 4x and 5x glazing, but more likely in hotels with a suitable location than in private house construction.

49 dB at the windows? I would like that too. But it's unaffordable, isn't it? :)
