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?
Do you remember when you could hear text messages over your speakers before getting the on-phone alert?
Freaking Nokias man… haha
And it was these speakers
They may not look very nice, but at least they didn’t sound very good.
Yup, I remember that 😄
