Do you often hear the ringing of switching power supplies and devices when you are in a quiet space? (lemmy.world)

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?

Even past 30 and with (mild) tinnitus, yeah my hearing is still great so I'm going to hear it. Light bulbs, chargers, the router etc.

Recently my computer's PSU has started randomly buzzing a not-quite-high frequency. It could be age (it's from 2019) though I'm pretty sure it's some kind of interference because sometimes it won't make any noise at all for days and I'm pretty sure my light bulb (an LED filament bulb which doesn't have much in the way of components) seems to also make different pitches of buzzing that coordinates with how much my computer PSU will buzz.

Anyways it bothers me, so as soon as I post this I'm going to power-down and unplug my computer and switch to a different device for the next day or so.

Since I got older this got better. One benefit I guess?
