Abstract
The invention relates to an acoustic diagnostic system and an associated method, wherein the system includes a sensor mechanism to convert mechanical vibrations into electrical signals. The acoustic diagnostic system furthermore includes a signal conditioning unit to amplify and low-pass filter the electrical signals and an analog/digital converter to convert the amplified and low-pass filtered signals into discrete digital data. In addition, a signal processing unit, which performs signal analysis, extraction of characteristics, and classification of error classes and/or quality classes, which are associated with a respective test object of the digital data, is provided. Finally, the acoustic diagnostic system includes an archive to automatically archive an occurrence and a frequency of the error classes and/or the quality classes. The diagnostic system preferably includes controlling means that control the production process for the manufacture of the test object.
