I have a heart condition that I get an ECG (electro cardiogram) done for every 6 months or so. It's just an ultrasound on your heart. They always take mine from a bunch of different angles and a bunch of different types of pictures.
But I was recently in the hospital and told the technician that their machine was loud. She looked baffled. I told her I can hear the ultrasound and hers is the loudest I've encountered. Apparently I'm the only person she's ever done work on (or however to say that) that's been able to hear it.
So I guess that is my super power. Or I'm just autistic, as apparently many autists can hear very high pitched noises.
But the ultrasound is pretty cool. The frequencies and the pitch will change depending on what photo mode they're in. Like a doppler mode is all pewpewpewpewpew while the normal mode is all eeeeeeeeeeeee. Lol. It's hard to explain.
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?
