Nice XD

At the volume I have my games and music, I rather doubt it. :-/

No, really. It is very common for individuals on the autistic spectrum to have above average acuity of high frequency sound.

They were in his cereal.

Unless you’re autistic. We don’t lose the top end of our hearing for some reason. Those “mosquito” devices can trigger my migraines, at 43 years old.

“Coil whine”.

The inductors used in the power regulation circuitry physically vibrate due to the electromotive force the part relies on to function. Changes in the load on the power supply changes the characteristics of the vibration, allowing audible detection of the variation.

The physical vibration slightly alters the electrical characteristics too, which is why inductors are glued down or “potted” in some equipment to try and negate this effect.

Edit: The inductors on your graphics card can whine too, this generates noise on the ground line of the whole PC which is then amplified by cheap sound devices, which is why you can literally hear the mouse moving on the screen on some PCs.

Ah, the “Mosquito” device.

I have strong feelings on those things. Strong enough to drill holes in one while up a ladder wearing a visi-vest.

Side note: It’s amazing how invisible you become while wearing a high-vis vest and a hard hat.

Another one!

It’s a common autistic trait, FYI 💛

I can still hear the bats pinging for insects round the back gardens. I was 43 last week :-p

Diagnosed autistic?

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. :-/
