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!

and also that it is noisy Noisy in what way? Noisy to what extent? Under which conditions? Under what building-related circumstances?

louder than normal See above. What exactly does "louder than normal" mean?
The world is not just black and white. Although there is a trend to reduce every situation to these two states, this almost always fails—especially with complex topics like building physics and acoustics. Nobody would come up with the idea to perform an airtightness test using a bicycle pump and a wet finger and then declare the house "not airtight."

How can I find out if the issue is with the windows or the wall construction?How about putting your ear to the wall and then to the window? That works great!Snowy36 schrieb:
whether replacing a window makes a difference by finding out if the noise comes through the glass or the wall. Sure, you can identify and classify installation defects or improperly executed component connections by simply pressing your ear to the surface. Then, of course, address the issue by replacing the window with one that has a higher sound transmission class (STC).
