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 clarify. You have a house still under the 5-year warranty period and you think it’s too noisy.
Instead of commissioning an expert report, which could identify the causes and allow you to have the builder fix the issues under warranty, you simply want to replace all window panes yourself?
And if that doesn’t help, you’ll move on to the walls? Exactly my point! We’re talking about a warranty defect that needs to be proven. Certainly not by replacing the window panes at your own expense, especially since that would void the warranty here.

Has anyone here actually done this? Called in an acoustician? Is that even the correct term? When I search on Google, I only find hearing aid specialists.
What exactly does this professional do, and how much does it cost? Do they really measure what is resonating and how?
For us, they only wanted 800 euros just to check if it’s noisy, which doesn’t help, because I can measure that just as well with my phone... Such a person is called a building defect expert. It has nothing to do with acoustics, but rather with whether the house was built according to recognized technical standards. If it wasn’t, there is a right to (free) corrective work.

Something like a building defect expert. It’s not about the acoustics, but whether the house was built according to recognized technical standards. If not, there is a right to (free) repairs. People always rush to get an expert instead of thinking for themselves.... that’s how they make good money.
The original poster definitely wouldn’t just replace the window if they believed there was a building defect!
Vicky Pedia17 Jan 2020 17:06This is the legally precise way! And it is looking for an answer.

Yes, always get an expert right away instead of thinking it through yourself... that's how they make good money. The original poster surely wouldn’t just replace the window if they thought there was a construction defect!You seem to know a lot of people. And if he is replacing the windows for a valid reason, then it was definitely a defect! Otherwise, it would just be wasted money. It’s easy to speculate from a distance, especially when it’s not your own money.Vicky Pedia schrieb:

I can only look at your "posts" with disbelief...
