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?
I play electric guitar a foot from my computer. I hear all kind of noises through my amplifier. Scolling with my wired mouse makes a noise through it. I also know my phone is goimg to ring before it does because the cell,signal makes a noise through mu computer speakers.
You’re correct that it’s not the high pitch sound from the old days. Now it’s more like a,low pitch hum. But it’s still there.
Cell phone incoming signals: dit dit dit…dit dit dit…dit dit dit…buzzzzzzzzzz…dit dit dit…buzzzzzz…ringtone.
Exactly.
