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?

    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.

      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”

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

      Yeah I don’t even hear the big 40A power supplies at work, usually 3 or 4 of them in a row on din rail.

      The variable frequency drives are a different story, sometimes those sound like the worst high frequency you’ve ever heard in your life. But I don’t even hear those all the time anymore, depending on the drive.

      I take steps to make sure my tinnitus isn’t getting worse. But about all you can do is try and protect your ears as best as you can. Once it’s there, it’s there to stay

        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.

    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 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

        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.

    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.

      Curious. I thought that buzzing from cellphones was TDMA induced, which isn’t really a thing since… LTE, I think? I’m wondering why you still get this. Older phone, older network/infra…?

        You’re correct that it’s not the high pitch sound from the old days. Now it’s more like a,low pitch hum. But it’s still there.

    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.

    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.

        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.

    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…

    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.
