Kitty, I just ran into that one yesterday...

our power was flicking on and off all day (the corporation wants an increase in the electricity rates)

and the BLEEPING BEEPING of the UPS drove me outside to seek my husband to shut it off !!

I know how to safely shut down my own equipment, but his is a different kettle o'fish.

and it wasn't the "regular" beeping... it was an ALARM, a full-on howl, due to the brownouts, surges, and constant fluctuations occurring.

so, yeah, I know what you mean... it was the pitch, combined with my inability to DO anything constructive about the noise.

babies crying get me too, and certain dogs, and the sound of brakes screeching.

I don't know if it's a hearing problem connected with my MS, or my advancing age, or my irritability of late due to hot flashes, night sweats, and lost sleep.
