Cochlear reflectance (CR), the cochlear contribution to ear-canal reflectance (ECR), has theoretical advantages for cochlear modeling. Comparisons between measurements and models may lead to improved clinical interpretation of cochlear status and provide a basis for making improvements to the models. Simulation of ECR was performed using a combination of (1) an ear-canal model, (2) a middle-ear model and (3) a one-dimensional cochlear model. Simulated CR was the ECR difference between active and passive conditions of the model. The model simulation results were compared with measurements of both ECR and CR in both the time-domain and frequency-domains. Disparities between measurements and model provide a basis for improvements in the model. Substantial agreement between measurements and model suggest that CR is consistent with linear coherent reflection due to random impedance perturbations along the cochlear partition.
