Just a little story...
Beeps and other tones of a kilohertz or so within a room with hard walls
are most amazingly non-directional, and can be remarkably hard to
locate. I spent a couple of hours over several days trying to work out
why my server seemed to have acquired an alarm set for midnight. I
eventually found that I had picked up my radio clock/weather station
and had inadvertently pushed a button which enabled an alarm which
defaulted to midnight, which I didn't know the thing could even do...
