Ah yes. Knowledge of jamming and making EMPs is not that complicated. Also, "hidden camera detectors" and "bug detector" abilities can be magnified applied to detect drones from a long way away.

Now thats interesting.
I know there are studies to detect tornados before they form based on their "inaudible" infrasound signature. I wonder if the same is possible with drones? I figure military drones are already designed with a small IR and radar profile, and some are designed to be hard for people to hear. But "hard for people to hear" is different from "hard for microphones to detect."
The noise profiles are classified, but yes. Acoustic detection is very easily accomplished.
You can build one very inexpensively, with a phantom powered microphone with the signal put through an FX processor and manually listen. If you have the noise profiles, you can automate it.

Too bad compression standards on youtube videos probably cut all that out, because theres tons of video of military drones from all sorts of nations and manufacturers. Landing profile is probably different from cruising and diving profiles anyway.
