I can hear ultrasonic sounds. And it’s not pleasant.
Maybe you need to get checked for tinnitus, because it’s literally impossible for humans to hear that frequency of ultrasound
Not necessarily I have tinnitus but certain ultrasonic sounds I can hear that are at the lower range of ultrasonic
Can you hear electronics hum? I can, especially when it’s quiet. Doing hearing tests, I would hear when they turned on the sound, but not be able to hear the actual sound. Idk what it is, but pretty sure it’s not ultrasonic sounds.
Uh huh… The Oxford definition literally says that’s untue.
of or involving sound waves with a frequency above the upper limit of human hearing
Not everyone has the same hearing range (it tends to get worse as you get older, hence those ultrasonic teenager repellers that people claim are for cats). If a device is running at the very low end of what we consider ultrasound and OP can hear higher than most then maybe they can hear the sensors. I would be surprised if an ultrasonic sensor was running this low though.
