The organ of Corti (OoC) is an active structure in the inner ear that transduces vibrations of the basilar membrane into signals in the auditory nerve. It has amazing sensitivity, being able to detect signals smaller than thermal noise. We present a set of simplified models for each of the components of the OoC that is able to reproduce this sensitivity. A key property that enables this performance is critical-oscillator behavior. The model for each component of the OoC can be modified independently and the influence of this change can be assessed.
