Abstract: A method and an analysis system for determining a state of a diaphragm of an ultrasound sensor during operation is disclosed. The diaphragm of the ultrasound sensor is excited with a first excitation signal in a predefined first frequency profile. Based on this, a first voltage profile, which depends on a frequency of the first excitation signal, is measured. Analogously, a second voltage profile is determined by applying a second excitation signal to the diaphragm and then carrying out a measurement. These two voltage profiles are shifted so that respective positions of maxima of the two voltage profiles are matched to each other in a predefined frequency range. A third voltage profile, which runs between the shifted first and second voltage profiles, is determined. Based on the third voltage profile, electrical parameters are determined by a model for continuous excitation of the diaphragm to determine the state of the diaphragm.
