High-pitched buzzing sound/noise with Apple Studio Display

I've had the same problem after I bought the new Apple studio display. Likely, I found a solution by 80% though the noise is still coming but with that kind of noise I can easily work with Apple display.

So, the solution is to broadcast an electricity through the power transformator - In my building there is a common 220V as a result converting it to 110-120V it helps to decrease the buzzing noise from Apple display.

I use a simple power transformator with 2 outputs for 110-120V and 220V but you can find the same or more complex.

I suppose it also works for the one man from youtube with the same issue.

NOTE: unfortunately, It doesn't remove the whole noise affect, but I repeat It reduces the noise enough for a sort of comfort usage.
