A technique that enables people to hear ultrasonic sources above 20kHz

I wonder if you could hear bats directly by having a headset / amplifier that contacts your skull rather than putting a speaker over your ear. It’s been reported that humans can hear ultrasonic frequencies via bone contact. (I’d speculate identifying the source direction doesn’t work though.) https://en.wikipedia.org/wiki/Ultrasonic_hearing

I can hear bats normally. I have a freakishly large hearing range.

There are definitely bats that produce chirps (partially) in the human-audible range. You don't need above-average hearing to notice 15 kHz sounds, which appears to be the lower end listed in some source. Most echolocation happens way beyond human hearing range though.

That's cool! How high can you hear? I can't hear up to 20k anymore. Can you tell where high pitched sounds are coming from?
