It was quieter than I expected, even from a couple hundred meters away. Once it was further away it probably dropped to around 60dB, but the frequency (pitch) of the sound was still distinct and therefore remained noticeable above the background noise of the port.
My preconceived expectations of a drone flight also left me caught off guard by the larger moment of inertia. The cargo bay "swayed" during the flight instead of making instantaneous and zippy corrections that I've become accustomed to seeing small drones perform. Looked super alien.
