Electrostatic actuators are designed to simulate the pressure response of condenser microphones. Oscillating electrostatic force is exerted in front of the microphone diaphragm, providing the consequent response of the microphone. By applying an oscillating electrostatic force - sweeping over a frequency range from 100 Hz to 200 kHz - the pressure response can be tested.
