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!

One square meter of gypsum veneer weighs about 18 kg (40 lbs).
That is significantly more than a gypsum drywall panel.18 kg (40 lbs) is still practically nothing. I wouldn’t have high hopes based on that.
Also, you have to be careful not to attach too much weight to the walls. Otherwise, it might come vi
Maybe you could try using lightweight concrete cladding. However, it might be too heavy for the gypsum fiber boards. You don’t want them to fall off again.
