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?

Everyone with fully functioning ears can hear it if they pay attention. Just a reminder to protect your hearing!

Inside your ear are hair cells that detect sound. You're born with the only hair cells you'll ever have, and damage to them is irreparable. Hair cells naturally sustain damage over time and people's hearing decreases as they age. This process is accelerated if someone constantly listens to things at loud volumes. So, maybe don't turn it up to 11!
