Case 1. Female user with quasi-normal auditory behavior. All electrodes show ECR morphology as described in Fig. 1 and ECR amplitude growing as test tone pip intensity level increases. For the same test tone pip intensity range and similar current dynamic range, the apical electrode shows higher growing slope, 0.5 µV/dBHL, than basal electrode, 0.1 µV/dBHL. Threshold intensity of 30 dBHL for apical electrode, and 20 dBHL for middle and basal electrodes
