Abstract

A system and method are disclosed which utilize robotic analysis of acoustic data captured during operation of a device to evaluate the operation of such device. An acoustic capture sensor is implemented within a device, such as a paper handling device, automobile, or any other device that generates detectable sound as a by-product of its operation. The acoustic capture sensor captures sound produced by the operation of the device and converts the captured sound from analog to digital. The captured sound is communicated to a processor-based device that is operable to process the sound to evaluate the operation of the device. The processor-based device may be communicatively coupled to a data storage device that has empirical sound data stored therein. In this manner, the processor-based device may compare sound captured by acoustic capture sensor(s) within a device with the stored empirical sound data to analyze the device'"'"'s operation.
