I'm 300 feet from the street in my apartment and I can hear the buses putter along the road and board at the stop, car horns, backup beeping, truck hydraulic brakes, and heavy construction. I don't think an RC drone that sounds like a case fan is going to add much to the cacophony.

Except an RC drone doesn't sound anything like a case fan. It sounds like a swarm of hornets. Maybe that's why it is such a grating sound to human ears.
