All electrodes were enabled, but dead regions were simulated by setting certain electrodes inaudible. See text for details. For each condition of dead region size, electrodes that are audible (Adb.) or inaudible (Inadb.) are indicated in the first and second columns, respectively. Cutoff frequencies for audible electrodes are shown in the third column for each condition of dead region size. The same analysis filter cutoff frequencies were used for the “dropped” vocoder signal processing.
