    Why don’t they hear the drones/copters? Too much ambient noises?

    I don’t complain btw ;) I’m just curious.

      The high frequency sound from these small drones attenuates pretty rapidly. Even without hearing protection and tinnitus, they probably wouldn’t hear it from less than 50 meters.
