Figure 1: Average air conduction hearing thresholds for the right (R, symbol: o) and left (L, symbol: x) ears with the min/max range indicating minimal and maximal hearing thresholds for the NH listeners (panel A). Average air conduction hearing thresholds for the audiometrically better (symbol: △)/worse (symbol: ▽) ears with the min/max range for HI listeners with symmetric hearing thresholds (panel B)
