Abstract
Based on equations derived previously, the authors develop a method for determining the parameters of an electret transducer. With the approach described, it is possible to implement a nondestructive method for finding the parameters of an electret transducer. A formula for electret microphone sensitivity can then be used to predict the sensitivity variation versus variation parameters with time (i.e., by discharging an electret and simultaneous weakening of membrane tension)
