Zusammenfassung:	A method for monitoring a system, in which a plurality of acoustic images are recorded and compared at defined intervals of time over a period of time extending several weeks. A large system can be monitored reliably and with little complexity if the acoustic images each contain a plurality of acoustic image areas which are arranged in a spatially different manner, and, between respective recordings of the image areas of an acoustic image, an acoustic sensor is aligned with an image area, which is to be recorded, of a next image area by being moved.
