N2 - The measurement of acoustic emission data in experiments reveals informative detailsabout the tribological contact. The required recording rate for conclusive datasets ranges up to severalmegahertz. Typically, this results in very large datasets for long-term measurements. This in returnhas the consequence, that acoustic emissions are mostly acquired at predefined cyclic time intervals,which leads to many blind spots. The following work shows methods for effective postprocessingand a feature based data acquisition method. Additionally, a two stage wear mechanism for bearingswas found by the described method and could be substantiated by a numerical simulation
