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!

Where did he receive a special soundproofing guarantee? From your "posts," I can only look on skeptically...Not a special one, but the soundproofing according to recognized standards. If those are met, everything is fine; if not, corrections are needed. But as @mini_g! already said correctly, he should make the decision—beyond well-intentioned advice from my own experience, I can’t offer more.Snowy36 schrieb:
Use a stethoscope and test whether the sound passes through the glass or the frame?Of course, you can do that. If you want, you can even run around the house with a divining rod. If your contracting partner (builder, tradesperson, manufacturer) accepts that as proof of defects, all good. Or if that serves as your basis for deciding whether to make a significant financial investment and replace all the window glass or even the entire window throughout the house: even better.However, I find it problematic to recommend such an approach to someone still under the warranty period.

The energy saving regulation is to blameI’m out. Hopefully, the measure taken by the original poster will resolve the described symptoms and they can report the costs somewhere.Hello, I wanted to share an update. I have replaced the glass panes in some of the windows with soundproof glass. It has definitely improved. Hardly any outside noise passes through the windows into the house anymore.
The problem that still remains is the exterior walls. Unfortunately, they are quite sound-transmitting, and I haven’t found a solution for that yet.
A quick question: I have silicone resin render on the exterior insulation. Would applying a second layer of render help improve sound insulation, or is that a really bad idea?
