I notice echoes even in smaller spaces. Like rooms. Carpets don’t stop the echoes. These echoes are unique in homes. They always sound “metallic”. Like sound bouncing off metal. Hard to explain.

Any room that is mostly empty (regardless of curtains, rugs, carpet) will have that echo sound. But furnishings definitely mute it.

It’s not pleasant.

It’s distorted in a strange way like when people talk through a fan. That’s the closest way I can describe it.

Idk what causes it specifically. I suspect windows.
The glass is likely the culprit.

Also the echoes have a very short latency. But I’d be surprised if others havent noticed them.

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.

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.

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.

I can hear the muscles in my eyes when I look from side to side or up and down.

I can see lights flicker when others can’t.

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 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.

Mold, or at least some types of mold. Used to smell it on food but other people couldn’t, so just assumed it was something else. But did the experiment by putting things in their own containers and leaving them out for a while, while probably not the best sample size, the muffins that smelled like mold eventually visibly showed it.

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.

I see certain shades of blue as grey, while my partner can distinguish more shades of blue than the average person, leaving me often feeling like I’m being fucked with

I wear almost exclusively grayscale clothing, except for a pair of pants that are apparently navy blue, and a shirt that’s supposedly slate blue

When food is going to go off, or when an object has developed mildew/black mold, I can tell way before anyone else by smell.

The chemical most places use for drycleaning is perchloroethylene, or perc, which can contaminate groundwater if not stored or disposed of properly.

The ringing in my ears is my own personal sensation. There are many others with a ringing of their own, but this one is mine and it undoubtedly is as unique as my fingerprint.
