You either get a chop-chop-chop, or a bzzzt, both incredibly loud. It's not the engine that makes the noise, it's mostly the propeller/rotor. The only advantage of electric VTOLs is easier manufacturing and better control.
Well, for instance, if they could line up the harmonics to create a missing fundamental (eg with the addition of external sounds), they could make propellers present an artificially lower pitch.
Private-transport helicopters or equivalents have no place in cities. The gain is in no way worth the cost.
Its not just unreasonable because the person flying gets less utility that is otherwise lost. It is also an unfair form of theft.
There is also a lot of space on how you maneuver it on the landing and take-out, so you make less sound when it matters the most.
There is the entire thing about minimizing weight too, that also reduces sound, but it's also not clear how much can be done.
Overall, it's not clear at all how much noise the eVTOL planes will make.
