Plaster walls need to be the double-thickness type, AND have sound-proofing material between each wall. I've suffered a few piss-weak plaster walls in my time, thin enough to punch a hole through with my fist and strangle neighbour on the other side (never actioned).
Once I lived on the bottom apartment in a two storey apartment block. The floor boards were a nightmare and eventually we had to move. Upstairs footsteps across the floor were loud enough to wake us up, and I don't just mean squeaky boards, but just the thumping knocking sound resonation. Sometimes I could make out the words being said in their conversations. Never again.
Definitely depends on the construction type. I will say that floor-to-floor noise transmission in a 19thC brownstone is a tiny fraction of what it is in a mid-20th-C apartment block. In the latter, you can hear people moving furniture or turning on the shower multiple floors away on the far side of the building.
