    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.

      Annoyed by the commonly imperceptible sound an ultrasound machine makes? Possibly autistic

      Facinated by how and why the machine works while it annoys you? Definitely autistic

      I joke but im exactly like this too lol.

      I had this exact experience and tried to ask the technician about it. She didn’t understand what I was asking. I thought I was just explaining it poorly.

      Lemmy needs to stop trying to convince me I’m neurodivergent.

      That’s a wonderful superpower! I can hear cars or footsteps approaching before my friends realise them, but high-pitched electric mole traps and ticking clocks can be annoying. Listening to music with good hearing is like taking drugs though. You should check out well-mastered music, commonly going as audiophile music.

      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:

        Yeah me too. I think this is called “coil hum”. I notice it with things like usb-c thunderbolt ports. Often you can swap a cable or something and it’s resolved.

          I definitely can’t hear high frequencies (I’m assuming due to ear infections as a child, feels mildly unfair that other people my age get to hear and understand conversations better but oh well) but coil whine is a thing for me as well.

          Had a router once that would whine depending on the network packet rate. My computer screen makes a noise when displaying large grids like a screen full of terminal text or a mostly blank spreadsheet. The led lights in my bathroom make a noise and I often turn them off while transacting my business. My Bluetooth headphones make similar noises depending on the connection state but that one is probably interference and not coil whine

          It happens at all frequencies. Although you don’t need to be able to hear special frequencies for it, of course you’ll hear it in more places if you have superlucg hearing ^^
