Figure 2: Temporal loudness integration (TLI) at threshold (mean ± standard deviation, n=8). Detection threshold (DT) amplitudes in dB re single-pulse detection threshold (SP DT) of the corresponding electrode. Stimulus duration in number of pulses (upper axis) and corresponding duration in milliseconds (lower axis). The lower axis was cut to accommodate the single pulse condition, for which a pulse train duration (in ms) cannot be assigned unambiguously. The dotted line shows the average TLI in normal hearing with a slope of 6.7 dB/decade and a critical duration of 200 ms. Top: Apical electrode. Bottom: Basal electrode. Left: 1.2 kpps. Right: 25 kpps.
