Ear-type systems

Abstract

Ear-Type Systems are ones which mimic the behavior of the biological ear via electronic systems and circuit theory. The physiological structure of the ear leading to the architecture under investigation will be reviewed. From that a circuit theory based upon transfer scattering in four port structures will be introduced. Using stimulated emissions of the ear, the parameters of these structures are obtained and kom them various investigations proceed. For example one can locate damage to the inner ear and by taking inverses of the located sections in some cases the damage can be cancelled out. In other cases possible neural stimulation of the inner ear leading to ringing in the ear may be determined. Various circuits, such as switched current ones, to realize the transfer scattering matrices will be discussed.
