Do these statements not contradict each other? Maybe I'll ask my question differently:
I understand that structure-borne sound can be transmitted through the exterior walls into the respective other floor. However, the architect, structural engineer, and builder all tell us that this is unproblematic if the screed layerer does a proper job on the screed in the upper floor. He would basically have to be made aware to pay attention to certain things (sorry, I can't recall the specific measures right now). Are they all wrong in this claim?
One more piece of information: we are planning a 26 cm thick concrete-steel ceiling between the ground floor and upper floor.
Whoever wants to be crushed by such thick ceilings; once the sound is in the wall, the unfilled bricks act almost like resonators (kind of panpipes). The transmission within the house to other components generally has less to do with the choice of building material and more with mechanical (de)coupling. It depends on "floating" screed and "edge insulation strips": even small sound bridges are unfortunately very effective. Maybe my reading recommendation will also help you:
