Figure 5

Left panel (a) shows individual IC difference (ΔIC) thresholds for unity (1) reference IC as a function of participant age. Adjusted partial correlations (r) of thresholds and age controlling for better-ear four-frequency average hearing loss were statistically significant for the older HI participants (p < 0.05). The linear regression is shown for older (solid) participants. Right panel (b) shows individual ΔIC thresholds for unity (1) reference IC as a function of better-ear variable pure-tone threshold averages (BEA). Adjusted partial correlations of ΔIC thresholds and BEA controlling for age were not significant for the older HI participants. The linear regressions is shown for older HI participants.
