In order to test a hearing aid having at least one microphone, one signal processing unit and one sound transducer, a sound channel is produced between the microphone and the sound transducer. The electrical signal path in the hearing aid is interrupted, and a test signal is fed into the interrupted signal path within the hearing aid, is emitted via the sound transducer, and is passed on through the sound channel to the microphone. The signal received by the microphone is then evaluated.
