Background: The goal of the current research is to develop a model based on computer simulations
which describes both the behavior of the auditory nerve fibers and the cochlear implant system as
a rehabilitation device. Methods: The approximate method was proposed as a low error and fast
tool for predicting the behavior of auditory nerve fibers as well as the evoked compound action
potential (ECAP) signal. In accurate methods every fiber is simulated; whereas, in approximate
method information related to the response of every fiber and its characteristics such as the activation
threshold of cochlear fibers are saved and interpolated to predict the behavior of a set of nerve
fibers. Results: The approximate model can predict and analyze different stimulation techniques.
Although precision is reduced to <۱.۶۶% of the accurate method, the required execution time for
simulation is reduced by more than ۹۸%. Conclusion: The amplitudes of the ECAP signal and the
growth function were investigated by changing the parameters of the approximate model including
geometrical parameters, electrical, and temporal parameters. In practice, an audiologist can tune the
stimulation parameters to reach an effective restoration of the acoustic signal.
