FIG. 1.
(Color online) Masking levels (ratio of Masked/Unmasked thresholds, Tm/T0) for individual CochlearTM users plotted against probe delay (ms). Upper and lower sections show results obtained with 40% and 70% DR level maskers, respectively. Within each section, upper and lower panels show results obtained in MP and BP stimulation modes. Each panel shows data obtained on a different electrode. From left to right, individual panels show results obtained on electrodes located from base to apex along the intracochlear array. Within each panel, different symbols show results with different subjects (identified in the legend in the top left hand corner of each section). The lines show exponential fits to the data pooled across subjects for each electrode. Insets show the fit parameters and the estimated time constant (τ). In one condition (El. 10, 70% DR) it was not possible to achieve a reasonable fit to the data.
