Abstract

Um eine schnelle, einfache und präzise Prüfung eines Mikrofons (110), insbesondere eines dynamischen Mikrofons, mit geringem Schaltungsaufwand zu ermöglichen, wird eine Schaltungsanordnung (100; 200) zum Prüfen eines derartigen Mikrofons (110), insbesondere eines dynamischen Mikrofons, vorgeschlagen, die wenigstens eine PrüfsignalErzeugungsstufe (120), durch die das Mikrofon (110) mit einer Prüfwechselspannung (UP) beaufschlagbar ist, sowie eine Auswertestufe (130) umfasst, der ein vom Mikrofon (110) abgreifbares Messsignal (UM), insbesondere nach einer Vorverstärkung, sowie ein Sollwertsignal zuführbar sind und die zum Abgeben eines eine Information über einen möglichen Defekt des Mikrofons (110) enthaltenden Ergebnissignals ausgestaltet ist.
