From the Volocopter FAQ [1] (in somewhat charming Denglish):

> DOES A VOLOCOPTER MAKE LESS NOISE THAN A HELICOPTER?

> Yes, the Volocopter is much more pleasant in terms of its acoustics due to its design and above all much quieter than conventional helicopters.

Listening to the video [2], this doesn't seem altogether implausible - the sound seems ok, like a fan more than a chopper.

In comparing the Volocopter noise to helicopters it would be something with no main rotor noise and 18 heavily loaded open tail rotors:

My guess would be that the noise wouldn't carry as far due to the higher frequency but would be very loud closer in, again due to the higher frequency.

Interesting, could well be. So not a problem for people on the ground, but you'd want to have a good noise-cancelling headset while on board.
