Abstract:
A demonstration device for pre-operatively demonstrating an at least partially implantable hearing system for the rehabilitation of hearing disorders, said hearing system including an electronic audio signal processing unit, said device comprising: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, an electronic audio signal processing unit connected between the audio signal generator unit and the electromechanical transducer for driving the electromechanical transducer, wherein the audio signal processing unit of the demonstration device corresponds to or simulates the electronic audio signal processing unit of the hearing system intended to be implanted, means for storing a plurality of parameter sets for setting the audio signal processing unit of the demonstration device, and means for selecting and transmitting to the audio signal processing unit of the demonstration device any one of said plurality of parameter sets.
