Abstract:
In a method and a device for determining a leak in at least one system component (2.1 through 2.n) and/or a state of a system component (2.1 through 2.n) of a system, at least one section of one or more system components (2.1 through 2.n) is monitored optically. Sound emissions occurring in or on at least one of the system components (2.1 through 2.n) are detected, analyzed and localized, wherein acoustically localized sound emission areas of the affected system component (2.1 through 2.n) are also optically detected and analyzed.
