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 did when I was younger but I don't hear it since I hit around 30

[–] DudeImMacGyver@sh.itjust.works 2 points 9 months ago

Yes, but a bit less as I've aged probably because the higher frequency hearing we have starts to diminish the older we get.

[–] knfrmity@lemmygrad.ml 2 points 9 months ago

Yes, but generally only bad quality loud ones.

I hear some of them. There's a real cheap one my parents got with a security camera thats real loud to me, but they don't hear it.

I used to think I do, but I convinced myself I have a tinnitus.

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