Question: Ultrasound hearing

mattdman - Wed Apr 06, 2005 6:40 pm

I have a very strange and very unique power, as far as I know I am the only person able to do this. In my left ear I am able tohear ultrasound (sound higher than humans can hear). I can hear dogwhistles and a device in my Grandfathers garden that wards off foxes and cats by ultra sound. I was born with 2 small spotson my left ear that a midwife told my mother were "unusual". I was wondering if anyone had heard of ultrasound hearing in humans. Help appreciated. Matt

Hello Mattdman,

Humans usually hear frequencies from around 20 hertz to 20, 000 hertz or vibrations per second. Dog whistles have different ranges, usually around 5000-12000 Hz and the “hum” of fluorescent lighting you might hear is only 50-60 Hz. Sounds we normally can’t hear would be the vibrations from whales, dolphins, elephants, some fish, etc. It would be very interesting for you to get a hearing test, they would test from the lowest frequency upward and you would know your range. You may have a very unique gift.
