Learn It

The most common electret microphone uses a flexible piece of electret material as one end of a capacitive plate. This will change capacitance according to sound pressure waves vibrating it which results in a voltage signal that varies according to the sound signal. To learn more about electret microphones and how to use them in your next LabVIEW project, click on the hardware you are using in the Build It section!
