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
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.
People often believe they are hearing ultrasound, but instead are hearing clicking noise or sub-frequencies emitted from the capsule that are not actually part of the ultrasound.
sorry I can still here it.. I sometimes needs to go to the hospital for a check-up on my heart, and I can hear the ultrasound if the device is going over my head.
