I was worried about this too. I recently got a newest gen DJI drone, and was self conscious about flying it for this very reason. Turns out, with the quiet propellers installed it disappears into the urban background hum when it's 30m up in the air. I've also flown it in uninhabited wilderness (national park, two days hike to nearest anything) and even there it's about 80-100. Add any horizontal distance and you will find it very hard to locate the drone after looking down at the controller (at least until you get better at flying it and develop better spatial awareness).
