摘要： Devices, systems and methods are provided for calibrating a transducer. One exemplary method involves determining a transfer function for the transducer based on a measured response of the transducer to an applied electrical signal, determining a set of values for a plurality of response parameters associated with the transducer based on the transfer function, determining a calibration coefficient value associated with the transducer based at least in part on the set of values and a correlation between physical sensitivity and the plurality of response parameters, and storing the calibration coefficient value in association with the transducer.
