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?

Good ears? the question is when, not where, and the answer is half a lifetime ago.

How do you consume those ears and what do I have to look out for if I want some product that you could consider good

Seriously, stop being an asshole. Coil whine is a well-documented behaviour that creates a loud, high pitched noise.

As coil whine is at the very limit of what human hearing can accomplish, it doesn't take much until you're unable to hear it. So you're likely too old or went to too many concerts to be able to hear it.

How many concerts to I need to visit to fix this issue?

Even half an hour next to the PA without special ear plugs is enough to permanently harm your hearing.

That's easy - so this is the solution OP is looking for
