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?

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.

where I live now I think I hear it everytime I go into my dorm room that is very small sometimes it seems to sound way louder than other times and the sound seems to be easily drowned by other outside enviromental noises I have more experiences hearing that kind of sound but cant remember right now exact details
