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?

Reading people like you describe their tinnitus makes me think I have mild tinnitus myself... It’s not “loud” enough that I realize it’s there over the background noise of a house. But if things get really quiet, like in a power outage, or in a very nicely isolated room like a sound booth, I do hear a slight ringing that sounds extremely similar to CRT noise. I guess the years of blasting music in my headphones and metal/hardcore shows without earplugs didn’t help my case lol

Sometimes I wonder if my tinnitus is real or if we're just so heavily surrounded by whines nowadays that it seems like tinnitus. I've been in an anechoic chamber and the first thing I noticed was that my ears weren't ringing, but outside of that I have a near constant tinnitus-like whine in several frequencies that doesn't go away even when I wear some kind of hearing protection. It's weird.
