The invention concerns a process and a device for electrical stimulation of the auditory nerve by means of a broad-band, preferably analog, stimulation signal whose curve is similar to the speech signal and a pulse signal, both signals being processed from audio signals. To improve hearing capacity, the pulse signals are transmitted in phase with the positive amplitude of the dominant portion of the speech signal, i.e. with a frequency equal to the frequency of the dominant portion of the speech signal. If an analog speech signal is used, the dominant portion is generally the fundamental wave. The electrode is connected so that the above-mentioned positive amplitude makes the active electrode negative (cathodic), i.e. exerts a stimulating effect.
