I have heard (and still hear) the whine when I’m near CRTs, too. It’s one of the many reasons I’m thankful this is the age of LCDs and LED displays and such–much fewer CRTs around to hear that whine from.
The barber shop I go to still has an old Magnavox CRT TV that I hear the whine from.
I remember in high school, one of the computers in one of the computer labs had this really huge, old CRT monitor that would make a very loud “BONG! EEEEEEEEEEEEEEEE!” sound upon the computer being booted. I hated that particular machine, and the other kids would avoid it, too, unless it was the last machine in the room available.
