1. A system for monitoring the operation a device for the occurrence of an abnormal event comprising:
- i) a microphone acoustically coupled to the device, the microphone producing an analog signal corresponding to sound waves observed by the microphone;
ii) an analog-to-digital converter for receiving the analog signal and producing a digital signal corresponding to the analog signal;
iii) a processor for receiving the digital signal and, for determining whether the abnormal event has occurred.
