Depends; I’m a lot older now and deaf (but have tinnitus, yay) in one ear, but I could hear the flyback whine of old TVs. I can hear the odd switching regulator still, but most these days are switching waaaaay above even the best human hearing range.
50/60Hz buzz should be fairly rare these days except for some high power cases or some really poorly designed electronics.

Man, I hated that sound. A lot of computer monitors had it too before they switched to LED/LCD displays.
