Its seriously wild that you can do this!
Apparently, ultrasound machines can use frequencies that start just higher than human hearing, 20kHz.
Can you hear dog-whistles, bats, or other electronics?
Get a hearing test and call Guiness (c:
I hear bats, absolutely. I can hear electronics as well, and some are just so frustrating. I've never heard a dog whistle, as in I've literally never seen one in person, but there's a house near to me that has a warning thing when someone approaches their yard, probably to ward off dogs? But my god, it's loud and high. I try to avoid that route at all costs.
"I hear bats" - Astounding! 8]
It would be very interesting to get a hearing test done. One which provides you with a chart of frequency against intensity perceivable. I'd check that they are equipped to go over 20kHz first.
In the case of bats for me I think I feel the pulses of bats because it's quite powerful, more than hear it. It's probably undertone resonance or something.
I haven't heard any for a while and my hearing is deteriorating but bat numbers collapsed and I haven't seen them either.
