This part of IEC 61094gives guidelines for the design of actuators for microphones equipped with electrically
conductive diaphragms;gives methods for the validation of electrostatic actuators;gives a method for determining the electrostatic actuator response of a microphone.The applications of electrostatic actuators are not fully described within this standard but may
includea technique for detecting changes in the frequency response of a microphone,a technique for determining the environmental influence on the response of a microphone,a technique for determining the free-field or pressure response of a microphone without
specific acoustical test facilities, by the application of predetermined correction values
specific to the microphone model and actuator used,a technique applicable at high frequencies not typically covered by calibration methods
using sound excitation.Cross References:IEC 61094-1IEC 61094-2IEC 61094-3IEC 61094-5EN 61094-1:2000EN 61094-2:1993EN 61094-3:1995EN 61094-5:2001
