Cochlear hydromechanics can be approximated by one-dimensional lumped sections.
Evidence
The model contains linear and nonlinear networks. In order to understand the interactions between these two kinds of networks and to search for relevant approximations useful for a computer model, the model was first realized in analogue hardware. … The approximation of the complicated hydromechanic system by a one-dimensional model is rough but effective. It shows the important facts, although the subdivision of a continuous fluid medium into the sections of a hardware model necessarily creates discontinuities. In order that these artifacts be distinguishable from real facts, the number of sections is limited to ahout 8 per mm length of the organ of Corti, corresponding to 10 sections per critical band. — Professor Dr.-Ing.
