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?
A good night’s sleep, exercise, and a good diet make a huge difference to my ability to focus. It’s a shame that having ADHD means that I’m terrible at getting myself to exercise, eat well, and to sleep at a normal time, even when medicated. (Note that I haven’t watched those specific videos)
There’s a pretty great channel for ADHD on Youtube - the creator of all the videos above - https://m.youtube.com/@HowtoADHD - and I think she’s covered that topic.
