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:

Modern Guiness is corporate propaganda.

Off topic, but I’ve not seen that emoticon before (unusually left-facing too!) and it’s adorable.

I hear bats, absolutely. I can hear electronics as well, and some are just so frustrating. I’ve never heard a dog whistle, but there’s a house on my walk with my dog 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.
