ᐅ Improving Sound Insulation for Interior Walls and Ceilings

Hello,
I hope this is the right subforum; I wasn’t completely sure which category would be best.
We bought a single-family house, built in 2013, with a timber frame construction.
Now, the following issues are bothering us:
The interior partition walls are extremely noisy. The construction is as follows: drywall (gypsum board) 12.5 mm (0.5 inches), OSB 12 mm (0.5 inches), 6x8 cm (2.4x3.1 inches) KVH (structural timber) with 40 or 60 mm (1.6 or 2.4 inches) Rockwool insulation (according to documents Sonorock, some parts are insulated with 40 mm, others with 60 mm for reasons unknown), OSB 12 mm (0.5 inches), drywall 12.5 mm (0.5 inches).
For example, you can already hear even the slightest throat clearing or when someone places a cup in the next room, not to mention other noises.
Since we plan to renovate anyway, a messy, more extensive effort would not be a problem. The question is, what would be most effective for us?
We could leave the interior walls as they are and, for example, build an additional interior wall in front using calcium silicate blocks (structural support would allow it), or remove the partitions and rebuild with thicker calcium silicate blocks? Or simply add another drywall partition in the same construction method in front? There is enough space for these options.
Then we also have the ceiling issue: exposed beam ceiling, insulation above, screed, floor covering. Here, too, the noise transmission is very noticeable. We would like to start with simpler measures, for example, removing laminate flooring and laying carpet.
We would prefer to keep the visible beams at least partly. Of the 26 cm (10 inches) beam height, about 16 cm (6.3 inches) could be insulated and covered with Heraklith boards, so approximately 6 cm (2.4 inches) of the beams would remain visible. Or would a full insulation and a suspended ceiling be more effective here?
Unfortunately, the house planner was unable to provide much support regarding soundproofing improvements.

What a nice atmosphere here, truly a reflection of society Of course, it is appreciated when someone lightens the technical discussions with humor, like placing heavy stones on a wooden house.

Moreover, I don’t understand how a house built by a carpenter and a prefab house expert relate So far, you have spoken about timber frame construction without indicating it was a unique custom build. But whether it is industrially produced or not, the construction method remains the same. From my perspective, the prefab house expert is the ideal specialist to diagnose and recommend appropriate solutions regarding the causes and remedies of any perceived defects. Who else? (As I said, I would have also recommended colleague Zink here, if you were not in SH and he not in BY).
