FIGURE 14. Comparison of neural and behavioral ΔF2 thresholds at different vowel levels.

FIGURE 14

(a) Results obtained under quiet testing conditions, (b) Results obtained in continuous background noise. Behavioral thresholds corresponded well to neural thresholds predicted by d’ values of the best individual fibers. This information was conveyed by high SR fibers at low vowel levels and by low SR fibers at high vowel levels. To compensate for pinna amplification, vowel levels in free-field behavioral tests (upper abscissa) are shifted 12 dB relative to vowel levels in closed-field neural tests (lower abscissa).
