Try whispering when someone is shouting :)

If the difference is big enough it's like adding 0.01 to 10. You'd need a lot of drones to influence the total noise level noticeably.

From my experience (Fimi 8 SE ~ 300g drone) the drone is annoyingly loud at < 5meters, and becomes practicaly silent at >50 meters (at least I don't hear it anymore).

Use the mesh which they already need to have to timesync their onboard systems, and have that modulate the rotors according to their ambient awareness. Profit by having an ubiquitous PA booming down from the heavens above...
