Method for calibrating a micromechanical sensor element and a system for calibrating a micromechanical sensor element

A system for calibrating a micromechanical sensor, comprising:

• a micromechanical sensor element;
• a sound source;
• a sound receiver;
• and
• a control and processing unit, for calibrating the micromechanical sensor element, being configured to perform the following:
• ascertaining a piece of primary information, describing a motion-state of the micromechanical sensor element, by the micromechanical sensor element during a first time interval;
• ascertaining a piece of reference information, which describes the motion-state of the micromechanical sensor element, during a second time interval based on a first acoustic signal, which is emitted by a sound source, and based on a second acoustic signal, which is received by a sound receiver, wherein the first time interval and the second time interval at least partially overlap with respect to time;
• and
• comparing the reference information with the primary information to calibrate the micromechanical sensor element.
