  • 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:

    • I hear bats, absolutely. I can hear electronics as well, and some are just so frustrating. I’ve never heard a dog whistle, as in I’ve literally never seen one in person, but there’s a house near to me 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.

        It would be very interesting to get a hearing test done. One which provides you with a chart of frequency against intensity perceivable. I’d check that they are equipped to go over 20kHz first.

          In the case of bats for me I think I feel the pulses of bats because it’s quite powerful, more than hear it. It’s probably undertone resonance or something.

          I haven’t heard any for a while and my hearing is deteriorating but bat numbers collapsed and I haven’t seen them either.

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

      • It’s my favourite emoticon, the most calm and cartoony.

        I also created my own questioning emoticon about10years ago,

        what do you think of it "?

          Took me a second but I see it now - very cartoony. I like it!
