Zusammenfassung:	The invention relates to a device and to a method for dynamically calibrating pressure sensors. Pressure acting upon the pressure sensor is compared to a corresponding desired parameter by means of a device according to the pistonphone principle, from which a calibration value c is determined. The aim of the invention is to provide a method and solution which enables a primary calibration of the dynamic ratio of a pressure sensor to be carried out. This is achieved by the fact that the device is only statically determined by respectively a housing to actuator connection and actuator to piston connection, and the piston is sealed in the cylinder with respect to the ambient atmosphere by a seal and is moveably arranged in the seal, and the change in pressure corresponding to the actual valve is calculated.
