so, I was wondering what exactly is the annoying buzzing of light bulbs, power sockets and generally any things which work with electricity I hear all the time. as far as I know electricity can have extremely quiet sound or no sound at all, so what exactly it is? is it circuits and electrical parts working or is it something else?

To add on:
If electronic noise is a 50/60Hz signal, why is it a high pitched whine instead of a bass rumble, like you’d think the low frequency would indicate?
