Figure 6: A: Input levels resulting in loudnesses of 15, 25, and 35 CU for a hearing-loss compensated narrowband signal (UEN1) presented monaurally. Colors and symbols correspond to the same subjects as in Figure 4. Data points in filled boxes represent results from NH subjects’ left ears and HI subjects’ audiometrically worse ears. White boxes represent results from right ears (NH) and audiometrically better ears (HI subjects). B: Interaural input level differences between the two ears are shown in panel B. The black boxplots represent the differences between left and right ears for NH subjects. The dark gray and light gray boxplots represent the difference between audiometrically worse and better ears for the groups with symmetric hearing thresholds and with asymmetric hearing thresholds, respectively.
