    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.

      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?

      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.

        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 can smell your fabric softener, no matter how long ago you used it. Artificial perfumes of any kind just murder my sinuses. It suuuucks.

    I also can hear electronics, even just the lights, if that’s all that’s on. Maddening, because I can almost never find real silence. It’s why I love camping.

      I experience the first set of powers, and I hate it. Every detergent, shampoo, deodorant I use is “sensitive”, “baby formula” or whatever.

      And a few years ago some deodorant company started using some I guess artificial compounds that just pushes the air out of my lungs, it’s so bad. I can not only smell it, it digs into my forehead.

        Can you do that thing where you flex some internal muscle and hear a loud rumbling that I assume is rushing blood? It’s hard to explain. I think the muscle is related to the jaw, or maybe ear movement. It’s not externally perceivable, but it’s useful on an airplane.

          Is that something like swallow or gently blow through the nose with closing your nose? This is what I’m suppose to do to release pressure on my eardrum, but I have no idea what you mean.

      All lights flicker. Just mostly we can’t perceive them.

      LED flicker is most noticeable tho. Incandescent the least.

      Fun fact. They flicker at similar frequencies (per light output/lumens) but the light drop off is more dramatic for LEDs so we perceive it more.

      People who are epileptic or prone to migraines usually are bothered more by LEDs.

    I used to operate a drill rig for taking soil and water samples. I learned to read all the utility markings and to spot the telltale markings of previous drill work. I can walk around an urban area and tell you where all the gas stations and drycleaners used to be just based on a look at the pavement. In that sense I can “see” things others can’t.

    High pitched noises sometimes. I have an audio spectrum visualizer app installed to confirm these. But they can be pretty weird as they bounce around. You’ll get these heat spots. Unfortunately, I feel like my ears are degrading now.

    Anyway, dimmable LED lights are often a problem due to PWM. Only full brightness is quiet.

    Smell, I don’t even know what the hell that was. There is or was something in the back of one bus. I wouldn’t say it’s smell, but… something. Just a spicy punch that doesn’t quite let me breathe in. I noted down the license plate if I’ll experience it again to confirm it’s the same vehicle, but this wasn’t the first time, though unfortunately I didn’t copy it that first time. Same line though, so possibly same vehicle as well.
    But I am not sure if I was the only one, no one was visibly bothered, but who knows.

    Low light vision.

    I was always very sensitive to bright lights and sincerely fear I’ll go blind at my last years but I can see at higher definition under low light conditions.

    My vision stops processing color and I get higher definition of contrast. I’ve walked through dark areas with no difficulty, where others simply said they could not see a thing.

      Maybe everyone already knows this but you can generally see better in your peripheral vision in low light.

      Almost all of your color vision / cones are concentrated in a tiny central area of your retina.

      The grey scale / rods are dispersed around that.

      In some ways I think night vision is a kind of skill that some people might be better at than others, even if the mechanics of their eyes aren’t special.

        It should. Seeing in low light is a very useful thing. And we could dispense some of the light polution we create.

        Based on what I’ve read about senses, I think most of human sensory variance is born in the brain and is trainable to be much more sensitive than we’d generally expect possible given our comparatively weak hardware. Some of us have the supertaster gene, but no one comes out of the womb a sommelier.

    Apparently I am the only one who can smell this odor that is on dish sponges. It it harsh as smelling salts and is like burning chemicals of some kind. It is not on fresh sponges and doesn’t always develop on used sponges. I thought it might be a chemical reaction between the soap and synthetic sponge materials. I tried searching for it online but haven’t found an answer yet.

    Not exactly sense, but my brain’s processing. I can easily pick out the melody of only 1 instrument in music. It’s like Fourier transform but on instrument level.

      As a trained musician I do this too. But it also means the “skill” spills over into other situations. If I’m in a restaurant, instead of being able to ignore the hum of background conversations, I will hear (and subconsciosly bounce around focsing on) every side conversation.

      It makes listening to things VERY hard

        I taught myself to do this after reading about it in a short fantasy promo when I was little. An adult asks a boy what he can hear, and he says people talking, so the man instructs him on how to really listen to what is being said around him, to gather information without attracting notice. I’ve always wondered what that story was because I’d like to read the whole thing.

      I didn’t realize that’s not a thing everyone can do. There’s a part of All I Want for Christians is You that’s just someone mashing annoyingly on a piano, and it’s so disgusting that I love it. It starts at about 0:58 on the YouTube Music copy, and then changes at about 1:05. It’s such an annoying sound in isolation.

        I’ve been thinking for hours how to describe it.

        It’sa sort of echoing scraping noise. A sheet of plywood lying on the ground, being kicked down the road. Only it’s quite faint, I can only hear it when the room is quiet or when I’m trying to get to sleep.

    I don’t know what it is, but I can smell a somewhat metallic type smell on some specific people’s breath. It always smells very similar between different people. They generally aren’t very healthy, but no one seems to know what I’m talking about.
