First example depends on the quality of the building. I own several well-engineered ones in which you never hear the neighbours except in the worst cases - when having a party with dozens of ppl for example.

Nit many people have truely 'spare' rooms, you always have to make room for dedicated purposes like this. It remains to be seen if vr rooms will really be a thing, too.
