Pure-tone behavioral thresholds (dB HL) at 250 Hz (top), 500 Hz (middle) and the average of 250 and 500 Hz (bottom) as a function of ABR threshold (dB nHL) to a 250-Hz toneburst. Dashed horizontal and vertical lines, and the solid diagonal line serve the same purpose here as in Fig. 1. The best-fit line, correlation, and number of cases are shown in each panel.
