[Hic sunt dracones]

I am typing this at a Televideo 950 terminal and am listening to 
a high-pitched continuous sound emanating from the terminal.
It is near the upper limit of my hearing, maybe 15-17 kHz,
and is loud enough to be distracting.  I mentioned this to someone else 
and he said that all terminals do that.  Maybe his hearing is better 
than mine, because I never heard it on any other terminal.  
I seem to remember a letter to the editor of Byte magazine a year 
or two ago complaining about the same thing. Can any of you hardware
types explain this sound? Is it indeed universal? Are the makers of
terminals aware of this and do they try to minimize it?  For me,
this adds a new criterion for the selection of a terminal.
