A more important question is whine.  When we did a terminal search 
about six months ago, we discovered that about 90% of the terminals
we looked at produced a high pitch whine that about 10% of our 
people found very disturbing.  Strangly enough salesmen and supervisors
could not hear this sound.

I understand it comes from the flyback transformer, and is a function of
the scan rate. We finaly selected TAB terminals as they did not seem to do 
this (very high scan rate).
