Scope

This part of GB/T 20441 specifies: -- Design guidelines for electrostatic actuators with conductive diaphragm microphones; -- Confirmation methods for electrostatic actuators; -- Methods for measuring the response of microphones to electrostatic actuators. This part is applicable to the application of electrostatic actuators, including the following: -- Techniques for detecting changes in the frequency response of microphones; -- Techniques for measuring the impact of the environment on the response of microphones; -- Techniques for measuring the free-field response or sound pressure response of microphones based on the type of microphone used and the predetermined correction values of the electrostatic actuator used, without professional acoustic testing equipment; -- Techniques for high frequencies that are not covered by acoustic excitation calibration methods.
