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 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.

          Interesting! I haven’t had this happen with any speaker or amp in a good decade. I wonder what it is!
