I can hear CRT screens. They emit a high pitch noise that nobody else in my family can hear, I assume most people actually can hear it but never noticed it. My family used to think I was crazy or had tinnitus (jury’s still out on both) until they tested me by making me close my eyes and tell them if the TV was on while turning it off and on at random, with sound off. It was a weird test from my perspective, since I could hear it fine anyway.
So far I haven’t noticed a decay due to age, but if it had little use when CRTs were widespread, it’s now completely useless.
I used to be able to tell what refresh rate they were set to because everything below a certain point flickered. I’d ask people why their screens were flickering and they couldn’t see it.
Now that is a superpower. I’ve always thought the ability to see fast was such an interesting skill.
Think about it: you could go to the Olympics in a skillful sport like fencing or boxing, and defeat every opponent without much formal training simply because you can see them telegraph their moves. No anticipation or planning required, you just watch them come to you.
It’s very common for us 'spergs to have a very high frequency cut off on our hearing, all the way to old age.
I’m 43 and can still hear the bats chirping when they’re hunting insects in the twilight round the gardens. People think I’m making it up, until I point the bats out, tracking them by sound until they flutter high enough to see their silhouette against the sky.
CRT TVs and monitors used to annoy the hell out of me. The high pitched whine of the flyback transformer that runs the motion of the electron beam makes a very distinctive hiss. Like someone else on here, I could tell what refresh rate your monitor was running in by the noise it made.
That, plus an abnormally high flicker fusion frequency meant I had migraines every other day when I was working. :-/
Interesting, never knew that. I’m in my 40s and can still hear the annoying high-pitched whine from the speaker outside a shop near me that’s designed to keep kids from hanging around.
Should be an age thing. I remember at school that some teachers would leave the TV on when they were done showing something and the CRT noise would make us students crazy and we had to remind the teacher to turn it off.
It might happen with non-crt screens too. I remember a flat screen (LCD?) that made a different noise depending on the color it displayed. White and light colors made a lot more noise and if you had good ears you could tell the difference without looking. Not sure how they work though to explain this.

Do you do any competitive sport?
I used to hear it too, now I’m old and I can’t hear anything above 16KHz, maybe less now.
Try that with cheap mobile phone charges. They have an annoying coil whine.
When you have tinnitus, then you will know it. And then you probably can’t hear that CRT screen anymore.
About “crazy” I don’t know ;)
Diagnosed autistic?

So you will probably lose it at some point.
Some power-supplies also do this high pitch noise too and it bothers me a lot. Most people can’t hear it.
I could detect it as a kid, but definitely not past 25
I can still hear the bats pinging for insects round the back gardens. I was 43 last week :-p
