Ah. It's a drone discussion.
Is there any advance in drone tech to make it quieter? Any time I've been near a drone in operation, the loud buzzing hits a particular psychological frequency (probably the "it's a large flying insect!") that stresses me out.
I don't think I'm alone in this. Other animals seem to dislike drones.
I think most of us animals would mind them less if they were more pleasant-sounding, or closer to silent.
- petra 11y agoThere's a way to spin each propeller at 180 degree phase so they would cancel/reduce each others noise.
- danieltiIlett 11y agoHow difficult is it to do while adjusting each propeller's speed for steering etc?
- petra 11y agoI've only heard about for wing based uav's , not quadcopters. Maybe this is a good sign for Google's drones, which use wings, but rotate their rotors for landing.
