EVS-EN 61094-6:2005

This part of IEC 61094  - gives 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 include  - a 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.
