Abstract (en)
[origin: WO2021180583A1] The invention relates to a microphone circuit (1) that is characterised, for the purpose of damping resonance and linearising the proximity effect, in such a way that an impedance element (5) can be connected in parallel to the microphone. The impedance of this element is preferably between 20 and 1000 ohms.
