Abstract:
An at least partially implantable system for rehabilitation of a hearing order comprising:at least one acoustic sensor for picking up acoustic sensor signals and converting the acoustic signals into corresponding electrical audio sensor signals, an electronic signal processing unit for audio signal processing and amplification of the electrical sensor signals, an electrical power supply unit which supplies individual components of the system with energy, and an actoric output arrangement for direct mechanical stimulation of a lymphatic inner ear space, wherein said actoric output arrangement comprises an intracochlear electromechanical transducer; wherein the intracochlear electromechanical transducer operates according the principle of dynamic volume change as a result of dynamic surface enlargement or reduction of the transducer in conformity with an electrical AC signal controlling the transducer; and wherein the transducer is a surface oscillator having a surface, at least a major portion of which is designed to oscillate in accordance with a dynamic volume change of the transducer.
