Hello.
Our general contractor pointed out the issue of sound insulation and recommended the following to us. We are not extremely sensitive but don’t want the house to be unnecessarily noisy either. Therefore, I would like to ask for your opinions on this. It is a single-family house with two full stories.
Exterior walls: 17.5 cm (7 inches) hollow brick from the brand unipor with external thermal insulation composite system (ETICS)
Interior walls: 11.5 cm (4.5 inches) calcium silicate brick, sound insulation category 2.0
Floor slabs: precast concrete elements (filigree slab)
Interior doors: hollow core doors
Bathroom interior door (washer + dryer): climate protection door with sound insulation class 1 with Schallex
Utility room interior door (gas heating, controlled ventilation system): climate protection door with sound insulation class 1 with Schallex
What do you think? Would this be sufficient for someone with “average” sensitivity? I know that sensitivity is subjective, but I’m still interested in your opinions.

When it comes to component connections like ceiling/wall, screed/subfloor, and so on, some mistakes are much more significant than the difference between the laboratory values of sound transmission through material X or Y. What was the alternative that the general contractor recommended instead of the mentioned materials?

He will earn more on the shell construction than on the commission from the window supplier, so for him, the efficiency of the set of measures matters less than making sure you "invest" where it benefits his margin :-)
We haven’t gone through the windows with the GC yet.

Solid core doors are fully filled = more/continuous mass = sound insulation.

Look at any door program that lists the sound insulation rating.
In terms of stiffness, solid core doors are also superior. That doesn’t mean that hollow core doors are bad. However, with hollow core doors, check the door in raking light first—on cheaper models, the tubes often show through.
