In this paper, the magnitude ratio of voltages applied to neighboring electrodes can be created to generate virtual channels. Our model is established by use of an Ineraid electrode array with three half turns of a human cochlea finite element model. The stimulation conditions generate related activating function peaks along the Basilar membrane and between the electrodes, representing different pitches as perceived by the cochlear implant users. The results also show the best performances in the three stimulation strategies are the four current sources stimulations. The position C at rotating angle 90 degrees is the best position for the three "half turn" models. Finally, the modeling results with virtual channel performances are consistent with experimental results.
