In a method for testing a microphone for its operability, at least one loudspeaker is arranged in permanent allocation to the microphone and supplied with a test signal, the signal frequency of which is within the operating frequency range of the microphone. The phase difference between the microphone output signal and the test signal is measured and compared with a nominal value. If the phase difference is within a tolerance range of the nominal value, the microphone is confirmed to be operable and if not, it is not confirmed. The method is suitable for automating the test process which can be triggered and analysed at a location remote from the microphone.
