Abstract
The question has been investigated whether or not it is possible to design a stable active model of the cochlea without using a second tuned structure. First a “learning” feedback model with negative damping in the cochlear partition is considered. This model, however, turned out to be unstable. The second model is characterized by a constant negative damping of the longitudinal fluid motion. An analysis of the energy flow shows that this simple model is stable as long as reflections at the helicotrema can be neglected. Consequently a second tuned structure seems not to be essential for the stability of a model.
