You too huh? I seem to be the only person around my place of work who is
bothered by these. I can hear just about any ordinary VDU - in fact I find
it unpleasant to stay in the same room as one for more than ten minutes.
Colour PCs are the worst offenders.

Fortunately, these days I work solely with Workstations which, if they
whistle, do so on a frequency well above even my hearing.
Maybe I haven't been to enough rock concerts...
Not surprisingly I don't watch all that much TV either.
