Conventional testing methods often only detect damage at an advanced stage or require time-consuming dismantling work. Early and non-invasive detection of such defects therefore represents a major challenge in the field of vehicle diagnostics and condition monitoring. The detection of structure-borne sound (structure-borne noise) offers a promising approach here: by analysing the sound spectrum, characteristic anomalies or patterns can be identified that indicate incipient damage. However, the complete detection of the entire frequency range leads to very large amounts of data and thus to high demands on storage and evaluation.

Solution approach:
For efficient and targeted detection of structural sound, a segmented measurement method is used that is tailored to the chara ...
