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 used to hear all these sounds, but I'm 40 now so I don't hear them anymore.

43 years old here. I can still hear it. I think I put about 10-15 chargers in the bin because of the noise. I also really hate those anti-mosquito ultrasone emittors people put in their yards. I can hear them whenever I walk around the neighborhood.

Do you remember when you could hear text messages over your speakers before getting the on-phone alert?

They may not look very nice, but at least they didn't sound very good.
