Abstract
A media handling apparatus such as a cash dispenser apparatus (16) includes a plurality of sensors made up of microphones (38) and acoustic emission (AE) sensors (42) which are respectively arranged to sense the acoustic outputs of different parts of the apparatus. The apparatus includes data storage means (50) arranged to store digital representations of normal outputs of the sensors (38,42) respectively corresponding to normal operation of said parts, and processing means (4) arranged, in operation, to respectively compare digital representations of the acoustic outputs of the sensors (38,42) with the stored digital representations of the normal outputs of the sensors (38,42). On the basis of this comparison, the data processing means (4) makes a determination as to whether any of the sensors (38,42) has an abnormal acoustic output. In this way, an indication of the state of health of the apparatus (16) is provided.
