Mould, I’m always surprised at how few people can smell when food is mouldy. I’ve had people insist the smell is a chemical smell, until we’ve found the offending mouldy item (e.g. When someone’s left a cup of coffee on their desk and gone on holiday) and I reap the glory of being right.

I can smell carbon monoxide.

apparently no one i know can sense the chemical/marker(?) taste in artificial cherry flavouring like dr. pepper or cherry coke/pepsi

i seriously don’t know how anyone can get past that taste, so i figure people either enjoy it, or don’t notice it

I can smell iron in the soil from a distance (depending on how much there is), and if there’s a lot of iron I feel very sick, almost like I’m going to vomit, and I want to get away from it. There was one place like that where the closer I got the more sick I felt and the more iron I smelled, I could taste it like there was blood in my mouth, some months later did they start digging there and found a lot of iron.

I do not really like lager (love other types) for the same reason, the taste has a lot of iron in it especially some brands but I seem to be the only one who can taste it. I kind of rank lager as less or more irony taste lol.

Sometimes at some bars does one or multiple beers on tap taste weird and sweet regardless of type or brand. No one else of my friends seem to be able to tell. I where at a bar once where only one beer tap tasted as it should… The rest had the same sweet weird taste.

I also do not like coca-cola or Pepsi so my taste buds may just be weird.

Despite having tinnitus, I can still hear very subtle sounds and identify them.

• For example, a long, deep hum means a garage door is opening/closing.
• I can also hear (and feel) footsteps and movement from people around a building, even very subtle movement.
• I can also pick up on all the little creaks a building makes.

However, despite being able to hear subtle sounds, I cannot hear “no” sound or silence due to the ringing. :/

I can smell when a woman is pregnant. I’ve shocked several friends by congratulating them before they even took a test.

I can taste water, irl no one I met really can feel the different tastes of plain water but i can

The fucking documentation for the libraries we program with, apparently. Everyone else at work either just vibecodes or goes “aw I don’t know how to do that, it probably can’t be done :c”

I think maybe I’m sensitive to some bad smells other people don’t get. One time someone was demonstrating to a group (including me) making chocolate and it smelled like vomit to me and I had to leave. The others weren’t bothered.

This might be a personal preference thing rather than a sensing-something-undetectable thing but I’ve always hated the flavour of dairy—can’t stomach dairy milk, dairy cheese, dairy butter, etc. The vegan versions of these things are fine to me though because they don’t have that distinct “dairy” flavour whilst still having the other qualities of the product.

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.

Constant droning Like tinnitus except very low-pitched. Probably caused by intracranial hypertension.

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.

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.

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.

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.
