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?

Coil whine ? Yup. They told me it would go away as I got older and lost range of hearing. Still waiting for that.

Edit: typo
