Summary: ultrasonics


Most people who notice "ultrasonics" seem to work in technical fields.
My guess is that others never notice them even if they do get headaches.
Two places I run into these awful sounds is car counters (although I
haven't run into any lately living in Manhattan or the street noise
is too high) and department stores (I've heard they don't bother to
turn off the sonic motion detectors during the day.  No one believes me
when I say that's why I hate buying clothes.)
