    I could hear them too, when I was younger. I lost that frequency range of my hearing in my mid-to-late 20’s, which I’ve read is normal.

      Me too. And like the other guy, all of them, unless I’ve only encountered shit CRTs.

      I’ve also stopped hearing it in my mid 20s when I’ve no longer seen a CRT monitor anywhere. If I’ve lost that frequency I don’t know.
