A coworker and I once did a similar thing (Just a beep, no vocoder) to isolate a faulty switch. This switch had been causing horrible problems (data corruption style) for weeks and we just couldn't find it. It's the only time I've ever seen my friend violent or aggressive. Upon find the switch he calmly unplugged everything, and then threw the switch at a concrete wall. I understood the sentiment.
