A lumped-parameter model of a cross-section of the physical arrangement of the cochlear partition. The transverse BM motion being driven both by the pressure difference in the fluid chambers and the pressure due to the OHC. The TM moves transversely and is radially driven by the OHC via the RL. The forces due to the radial motion can be resolved into equivalent transverse forces and the radial TM degree of freedom can be represented as an equivalent transverse degree of freedom.
