It may well be that windows with poor sound insulation are a weak point and reduce the soundproofing. However, the sound insulation of solid walls is certainly not nullified as if the whole house were made of glass.

No, even as if it were made of nothing – the unsealed installation gap alone is enough for that.

No, it’s even as if it were coming from nothing - the unsealed installation gap alone is enough for that.

Then noise protection walls along highways would have to be designed as tunnels with locks at the entrance and exit. But they are just walls and open at the top.

According to a study, the columns should have a sound insulation attenuation 10-15 dB higher so that they are not worse than the windows.

Sure, if you have a joint that is not properly executed anywhere, sound will come in there, but you should be able to identify that it is coming in there....
