Is it physically possible? Theoretically like what is the quietest we could go?! Is it just the motor or is there some sound generated just by moving air around

  I've seen some people doing work on this [1]. I can't remember how much was actually making the drones quieter vs doing signal processing to remove the sound from on-board audio capture. [1] https://www.dotterel.com/ https://www.dotterel.com/

  If it's anything like e.g. PC fans, using larger, slower moving propellers is the way to go. But alternatively, just use a selfie stick, the previous biggest nuisance.

    that makes sense, same with turbines they are insanely scary huge. i follow reddit/r/megalophobia a giant 10 foot wing span drone would scare me!!!

  In theory the noise is wasted energy, so making them quieter should make them fly better too.

    that makes sense. like gears/metal grinding = friction i assume?
