@Arcadian_O@mavroudisv I'm thinking of something like a bat-detector, shifting the sound into human hearing range. -
Not a bad idea at all. We actually looked into active cancellation for a while, but it was too tricky...

undergrad project? combo beacon-detector and visualiser / audibiliser?

Happy to provide some samples with the original beacons! I guess, audacity could shift it to audible frequencies(?)
