Abstract
The microphone comprises a housing (), which has an inner volume () filled with a gas, an opening () of the housing, an acoustic sensor () arranged in the housing, a diaphragm () of the acoustic sensor located above the opening, and a heater () in the inner volume. The acoustic sensor may especially comprise a microelectromechanical system. The gas is heated from inside the inner volume to increase the pressure and generate a corresponding signal of the acoustic sensor (). This signal can be used for self-calibration of the sensitivity or for self-diagnostics to check the function of the microphone.
