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 used to hear all these sounds, but I’m 40 now so I don’t hear them anymore.
43 years old here. I can still hear it. I think I put about 10-15 chargers in the bin because of the noise. I also really hate those anti-mosquito ultrasone emittors people put in their yards. I can hear them whenever I walk around the neighborhood.
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 😄
