In order to substantially realistically pre-operatively demonstrate to patients having an impaired hearing the effect and sound impression of an least partially implantable hearing system including a first electronic audio signal processing unit, a demonstration device is provided which comprises an electromechanical transducer adapted for being non- invasively coupled from the side of the external auditory canal to at least approximately the center of the tympanic membrane and thus to the end point of the manubrium mallei for producing mechanical vibrations of the tympanic membrane, an electronic audio signal generator unit, and a second electronic audio signal processing unit connected between the audio signal generator unit and the electromechanical transducer for driving the electromechanical transducer, wherein the second audio signal processing unit corresponds to or simulates the first electronic audio signal processing unit. A further aspect of the invention is a process for preoperatively demonstrating the effect and sound impression of an at least partially implantable hearing system intended to be implanted.
