| Page Count: | 42 |
scope:
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.
