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?

Use a spectroscopic app on your phone

It'll help you identify the source of high pitch sounds

I once noticed an external HDD was making a high pitch noise intermittently, as the LED turned on and off. It was bizarre

Edit: spalling

I wonder if that spectroscopic phone app could hear the ringing in my ears

If it's actually tinnitus, no

If it's something that makes you think you have one, yes

I swear my tinnitus is so loud I'm surprised no one else can hear it 😭

Hope you can recover!

Had suffered sound damage prior, my ENT doctor said I was super lucky to not cross the line after which it would get irreversible.

Currently having no ear sounds above normal.

Objective tinnitus is a thing, though less common than subjective tinnitus. It is possible your ear actually is producing sound others can hear, though I guess only with a stethoscope, not the naked ear. https://nyulangone.org/conditions/tinnitus/types
