I'm curious, how many people are aware of these sounds. I have designed, etched, and built my own switching power supplies along with winding my own transformers. I am aware of the source of the noise. So, does anyone else hear these high frequency sounds regularly?

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....

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

[–] [email protected] 12 points 8 months ago

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

[–] [email protected] 1 points 8 months ago

I used to think I do, but I convinced myself I have a tinnitus.

[–] [email protected] 22 points 8 months ago (1 children)

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.

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

[–] [email protected] 17 points 8 months ago

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

[–] [email protected] 12 points 8 months ago

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.

[–] [email protected] 12 points 8 months ago (2 children)

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

[–] [email protected] 3 points 8 months ago (2 children)

Age related hearing loss can actually make you more sensitive to certain sounds. I have difficulty understanding speech but increased sensitivity to sounds including electrical buzzing.

45 checking in. I hate them

[–] [email protected] 6 points 8 months ago

It is never quiet enough in my house to hear myself think without difficulty, so it definitely never gets quiet enough for that.

[–] [email protected] 9 points 8 months ago

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 αƒš(ΰ² _ΰ² αƒš)

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

Where can I get what you are having?

[–] [email protected] 4 points 8 months ago (1 children)

Good ears? the question is when, not where, and the answer is half a lifetime ago.

[–] [email protected] -1 points 8 months ago (4 children)

How do you consume those ears and what do I have to look out for if I want some product that you could consider good

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.

[–] [email protected] 1 points 8 months ago* (last edited 8 months ago) (1 children)

My main laptop is making similar noises all the time, I think they come from the CPU.

[–] [email protected] 5 points 8 months ago (2 children)

The CPU itself doesn't produce sound, but inductors (coils) can. Therefore, when you move the mouse, the CPU power increases, potentially causing inductors to go into resonance.

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

[–] [email protected] 12 points 8 months ago* (last edited 8 months ago) (1 children)

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.

[–] [email protected] 8 points 8 months ago

My PC fucked with me with the coil whines.

Playing Metro Exodus with raytracing and shit? No noise.

Playing Grid 2, released over a decade ago? "Let me play you the song of my people"

[–] [email protected] 11 points 8 months ago

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.

Exactly what I was thinking hahahahhaha

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.

[–] [email protected] 5 points 8 months ago (1 children)

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

[–] [email protected] 9 points 8 months ago (1 children)

I have tinnitus AND can hear my lightbulbs buzzing. Follow me for more tips!

[–] [email protected] 6 points 8 months ago

It’s probably the type that’s brain side like mine. It’s not an ear thing but your brain has some reason for thinking you hear the ringing. But even so, I can still hear the slightest sounds. It’s bizarre because the ringing will be louder but I hear things that are quieter. It’s like having two sets of ears at once in those moments and is always unsettling.

[–] [email protected] 5 points 8 months ago

Same. As a kid my hearing was sharp enough to hear the high pitched sound my neighbor's tube TV made.

Now? 24/7 of this: https://youtu.be/lRxTBo7qxg8?si=32Vsxmux3p-y2Vow

I can hear my phone charging.

[–] [email protected] 8 points 8 months ago (1 children)

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.

[–] [email protected] 3 points 8 months ago* (last edited 8 months ago) (1 children)

I remember sometimes waking up in the middle of the night and start noticing/hearing a loud as fuck deep humming sound that seems to have some kind of hearthbeat if I just stand laying on bed doing nothing, I have lived in totally different places and I remember hearing the exactly same sound sometimes at night I just seem to notice that happens the same day I would go hiking to certain place, everytime I notice the sound at night it feels like the sound is leaking itself through the walls and reverbs like being inside something like a water pipe

[–] [email protected] 1 points 8 months ago* (last edited 8 months ago)

Could you be hearing the Hum?

Edit. This article implies that people can't hear it, but many people can, and, while it causes a mild annoyance with most of those that can hear it, it has caused severe disturbances in others.

  • wireless charger

Thankfully none else!
