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!

These are sound insulation panels made of cardboard filled with sand. Similar materials have been used for years in high-end speakers and work very well... We came across them while visiting reference houses, and according to the building contractor, they are supposed to work effectively.

Similar components have been used for years in high-end loudspeakers. That's funny. High-end manufacturers use all kinds of materials (and tend to develop very little themselves). Hawaphon does the same, by the way—I first encountered this when I was still "distributing" high-end equipment. The smaller the manufacturer, the more extravagant the "special materials" borrowed from other industries. The Phonestar basically looks decent as well, but unfortunately, the links to the technical data don’t work very well.
