Fluke

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. :-/

Not near enough to actually change a damn thing though, was it?

I mean shit, the company responsible is now trying to take down Greenpeace -the entire entity- in court over the whole affair, it is that confident in how fucked the US judicial system is.

They got to choose where to hold a trial with global ramifications, and tainted the entire possible jury pool by restricting it to some poxy little oil town that would cease to exist if not for the oil industry.

How many of you turned out to protest that?

They can eyeball all they want, the red states are also the US' welfare queens. They're poor AF and would be bankrupt in a couple of years.

How many cared when it was decided there would be an oil pipeline through the pittance they were relegated to? More land stolen, and everything around it polluted in time to add insult to injury.

Did you care then, just a few years ago?

They did. And created and taught others some of the most reprehensible methods of population control and genocide the world has ever seen.

Acknowledging it rather than denying it. Learning from the darkest parts of our history, to never have it be repeated is what I want done.

Ignorance of our history is why it keeps repeating itself. Gestures widely

"The government" offered money for the task, and thousands took that money and got on with the job.

"The Government" is people. Usually the worst, most manipulative self-serving people. It does what other people let it get away with.

Have you even looked at my comment history to decide what kind of person I am, or did you decide that purely from where I registered my account over a year ago?
