This paper deals with the forward and reverse multi-channel implementations of the Meddis's inner hair cell (IHC) based auditory models. During the forward model implementation, we have tested three different auditory models and used a suitable filter bank as a pre-processor to Meddis IHC model and calculated the auditory neural firing data for each channel.
   In the reverse model implementation and test phase, different sections of the model like Meddis IHC, half wave rectifier (HWR) and filter bank have been inverted. Using the outputs of the forward model as an input to the reverse model and regenerating the estimate of the original signal, the performance of the reverse model has been evaluated.
