Figures

FIG. 1.

Mean current levels (across subjects) needed to obtain “Barely audible,” “Soft,” “Most comfortable,” and “Maximal comfort” loudness for MP (top panel) and BP + 1 VCs (bottom panel), as a function of IPI. The error bars show ±1 standard error.

Image of FIG. 2.
FIG. 2.

Additional current (in dB re: 1 μa) required for a sequential VC to maintain equal loudness to a simultaneous VC (α = 0.5). Mean data (across subjects) are shown for MP and BP +1 VCs. The error bars show ±1 standard error.

Image of FIG. 3.
FIG. 3.

Individual and mean discrimination scores between simultaneous and sequential VCs for MP and BP + 1 stimulation, as a function of IPI. The error bars representing ±1 standard error. The dashed line indicates chance level (33% correct). Note that the average data (in the bottom right panel) excludes subject C16, as no BP data was collected for C16.

Image of FIG. 4.
FIG. 4.

Discrimination scores between simultaneous and sequential MP VCs, as a function of MP electrode discrimination scores for the same electrode pairs. The electrode discrimination data are from Landsberger and Srinivasan (2009) and Luo et al. (2010). The dashed line indicates the best linear fit.

CI subject demographics. The component electrodes used for the MP and BP+1 VCs are listed at right.

TABLE II.

Loudness-balanced amplitudes (in dB re: 1μa) used for VC discrimination. The simultaneous VC column shows the “Most Comfortable” reference amplitudes for MP (top) and BP + 1 stimulation (bottom). The loudness-balanced amplitudes for sequential VCs for the experimental IPIs are shown at right. For each cell for the MP stimuli, the total amplitude (on both the apical and basal electrodes) is presented. For each cell for the BP + 1 stimulation, two values are presented: (1) the apical channel amplitude, and (2) basal channel amplitude.
