how dos this acoustic system work, and how does it distinguish drones from other noise? Does it use any form of AI?
Drone propellers make a distinctive noise, which can be isolated quite well from background noise with FFT analysis. I doubt they'd choose to use AI for that, as classical methods work perfectly fine and need much less processing power.
