Abstract (en)
[origin: EP1181950A2] The system has at least one sensor for picking up sound signals and converting them into electrical signals, an electronic unit for audio signal processing and amplification, an electrical supply unit and at least one electromechanical output converter for mechanical stimulation of the middle and/or inner ear. An impedance measurement arrangement determines the mechanical impedance of the biological load structure coupled to the output converter. The system has at least one sensor (10a-10n) for picking up sound signals ands converting them into corresponding electrical signals, an electronic signal processing unit (12) for audio signal processing and amplification, an electrical supply unit (30) and at least one electromechanical output converter (16) for mechanical stimulation of the middle and/or inner ear. An impedance measurement arrangement (25) determines the mechanical impedance of the biological load structure coupled to the output converter in the implanted state.
