ᐅ Prefabricated house, poor sound insulation / high noise transmission

Hello,
I live in a prefabricated single-family house built in 2017.
Unfortunately, the walls in the house are very noisy.
For example, if you put your ear against the wall, you can hear people talking on the street. Also, when cars drive by, there is a booming sound inside the house because the exterior wall is probably too light or thin.
The exterior wall consists of 80 mm (3 inches) of polystyrene insulation panels, 12 mm (0.5 inches) OSB boards, 140 mm (5.5 inches) of interior insulation, and 12 mm (0.5 inches) gypsum fiberboards.
What options are there to have the construction company make improvements?
Would it make sense to have an acoustic report conducted?
I would appreciate any help!

Just to understand. You have a house within the 5-year warranty period and you think it is too noisy.
Instead of having an expert report prepared, which could identify the reasons and potentially allow you to have the construction company carry out corrective work, you just want to replace all the window panes yourself?
And if that doesn’t help, you’ll move on to the walls?
This is hard to understand, isn’t it?
Best regards, mini You do realize how much such an expert report costs, right? It’s not something you just do on a whim!

Hello, first of all, thank you very much for the replies. I will start by replacing the window glass with soundproof glass. I hope that will help somewhat.
Whether I then do something to the facade or double-layer the interior wall, I’m not sure yet. If anyone has any ideas on this, please feel free to share.
Best regards, Theo Hello Theo,
Where are you having the panes replaced and how much does that cost? We have also been considering upgrading our windows, as we are not satisfied with the current panes (32 dB).
Good luck

Has anyone here actually done this before? Called in an acoustics specialist? Is that even the correct job title? When I google it, I only find hearing aids. Sorry, the field is called acoustic construction. Google that. And yes, I have hired such professionals before; they do exist.

Good luckIt’s best to have window glass replaced by a glazier. Regards, Theo

It’s no use because I can measure that just as well with my phone... No, you can’t.

How do you figure the acoustician will tell you why it’s noisy? Because that is exactly the job of a building acoustician. After measurements, reviewing the contract documents, construction and execution plans (wall and ceiling compositions), and examining the hopefully available photo documentation of the build, the expert can usually tell you very precisely where the problem lies.

What he does, you can do yourself, right? Again: No.

And you can also just google your wall build-up and your windows and see what sound insulation ratings they have. That won’t get you anywhere in assessing whether there is a construction defect. Especially not if you want to assert any claims. And no, claims are not made with a random number generator on a phone. Doing so only makes you a laughing stock.
He will be able to tell for himself whether the noise is coming through the window or the wall ... and also that it is loud ... he doesn’t need anyone measuring exactly how loud it is down to the decimal.
He doesn’t need an expert report or anything like that for this ... only if he then finds that the noise level in his place is louder than normal, THEN he can file a complaint or report somewhere. But maybe he will also find that what he hears is completely normal.
