I have tinnitus and it sounds just like power supplies, except it comes from nowhere. So, when I hear the squeal, I turn my head. If the squeal noise follows the movement of my head, tinnitus. If it stays put, power supply!

It's like skunk and pot! (I'm in Canada, it's legal and everywhere.) If I smell it, I look around. If I see a burrow, skunk! If I see a dozy looking dude with red eyes...

It's especially common among people with Autism/ASD and ADHD to hear noises other people often don't hear. Like those LED light bars, or coffee pot crackling, or electricity from appliances. For ADHD I've seen a few people claim that those sounds are just as audible for everyone else, but everybody just subconsciously filters it out and doesn't notice it, while people with ADHD are easily caught by it. I assume for ASD it would be somewhat similar – plus Autistic people are a lot more susceptible to sensory issues, although people with ADHD also often have fucked up senses, which can make noises like that a LOT more noticeable (and even problematic/headache-inducing/stressful/painful).

My father used to make fun of me for saying that I could hear the TV on even if it was muted, or that I could hear the furnace 'scream' before it came on.

One year, I got as a gift for Christmas, a handheld recorder and a fancy microphone from my stepfather a university music professor And that recorder could actually record the sound which he was able to show me on the computer.

That was like 25 years ago, I've been working with computers ever since, and now I am familiar with many many many devices that make high pitch whines.

Coil whine ? Yup. They told me it would go away as I got older and lost range of hearing. Still waiting for that.

Edit: typo

Tinnitus crew checking in

I did as a kid, but my tinnitus covers it up now.

Yes. I can hear to about 18kHz, so cheap USB chargers are no longer allowed in my house....

Worse, the EV chargers I used to work with had PEMs switching at 10kHz for the US UL variants. EVERYONE could hear those!!

Test your hearing range with this if you want...

I used the 10kHz tone to annoy the eng dept in the office till they changed the PEM switching freq to 20kHz....

Yes. They drive me nuts. My family had a PC that would buzz whenever you moved the mouse. We have a bunch of cheap LED lamps in my apartment and every one has an especially loud transformer.

Not anymore.Age.

When I was a kid I hated going to the city art museum because all the humidity and temperature control devices emitted this awful high frequency noise that made me nauseated.

I can't hear the "mosquito" pitch noise emitters used to deter teenage loitering in some cities anymore. I kept that longer than I thought I would.

Yes, often. It doesn't really bother me that much, plus tinnitus generally overwhelms those sounds.

Yes and it drives me bonkers. I've had to leave rooms because the noise was just too loud

Not since I developed tinnitus...

Used to, until the tinnitus kicked in.

Despite me having tinnitus, I hear those sounds very clearly in quiet environments. They annoy the crap out of me...

I play electric guitar a foot from my computer. I hear all kind of noises through my amplifier. Scolling with my wired mouse makes a noise through it. I also know my phone is goimg to ring before it does because the cell,signal makes a noise through mu computer speakers.

Yes, and CRTs as well.

I used to hear this...back when I was in my 20s 😭

Yes. On a side note: do not buy hp printers they are really bad for their power supplies.

Yep. I was told I’d stop hearing it as I got older but I turn 40 next month and I still hear it.

please don't make me aware of more sounds I wasn't aware of before, I have enough of them already

I can hear coil whine from my PC's graphics card, but that's it.

Edit: Also our home stereo system (not the speakers) when it's turned on.

I used the have a PC that ran Windows XP, and when I moved the mouse, sound was heard from the speakers. It probably had a cheap sound controller on the motherboard.

Yes some of my smart bulbs make that sound when they’re off or on low power. I’m 38. I do have a mild tinnitus as well but it’s on a different frequency so I hear the difference.

Yes, I can hear them. Usually it’s not a problem but I have had 1-2 power adapters that annoyed me.

I just remembered that the Dell docking station I’m using makes a sound when it processes data. I can literally hear my mouse move.

Don’t buy Dell.

I don't think I own anything that makes noise like that anymore, but we used to have a big TV a few years ago that I could tell was on or off from the other side of the wall.

E: I just remembered that my speakers sometimes make noise if I listen at a certain angle and last week I heard someone's iPhone charger make a ringing noise while sitting on the socket so I disconnected it.

Two of the best investments I've ever made were good quality PC fans and SSDs instead of HDDs. Now, the loudest noises I hear come from my tinnitus.

Got the fans in my pc turned up higher than needed just so i dont heat the coil whine.

I used to hear tv tubes, power supplies and all sorts of high frequency noise. These days I mostly just hear tinnitus. EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

My air fryer has a blinking light whet it's on standby. Well, when the light's OFF, I can hear a high pitched noise. My partner is 4 years older than me and she can't hear it ლ(ಠ_ಠლ)

The transformer of my electric shaver makes a similar noise too.

I tend to flip off powerstrips at night because of that exact sounds. And also because I think my devices could be listening.

I'm 56, wear earplugs at night, and still hear an intermittent electrical noise. It's not a high-pitched whine, more like a low hum. I live in an apartment complex so it's likely the wiring. I have hyperacusis.

I used to hear all these sounds, but I'm 40 now so I don't hear them anymore.

I can't hear it but I can often tell when it clicks over because it causes a spike in my tinnitus.
