Figure 1: Behavioral thresholds in dB HL (upper panels) or dB SPL (lower panels) plotted as a function of frequency (Hz). Mean thresholds (black lines) and 95% confidence intervals (grey shaded) are also shown for the NH group (N = 21 for dB HL and 20 for dB SPL). Horizontal dark grey line at 20 dB HL indicates the lower bound of normal hearing. Thresholds for HI participants presented by test ear (right, circle and left, 'X'). The audiometric phenotype (based on dB HL thresholds) for each of these individuals is indicated
