Abstract: A method for determining the moisture within a cooking chamber of a cooking device has the following steps: a) an acoustic oscillation generating in a resonance chamber, b) a control unit receiving the signals picked up by a microphone in the resonance chamber, c) the control unit determining the frequency spectrum of the acoustic oscillations present in the resonance chamber on the basis of the received signals and determines the speed of sound within the cooking chamber on the basis of the frequency spectrum, d) the control unit receives receiving a temperature value; and e) the control unit determines the moisture within the cooking chamber by means of the temperature value and the speed of sound.
