Results of experiment 1 showing the magnitude of the perceptual-separation advantage for each interferer type, averaged across TMR, for (a) the NH listeners presented with unprocessed stimuli, (b) the BI-CI listeners, (c) the SSD-CI listeners, (d) NH listeners in the bilateral-vocoded condition, and (e) NH listeners in the SSD-vocoded condition. Error bars indicate ±1 standard error of the mean across listeners.
