Figure 2: DPOAE levels (dB SPL) for each HI participant by DP order (2f1-f2, left and f2-f1, right) as a function of f2 (Hz). Black and gray lines depict mean DPOAE and NF levels, respectively for the NH group. The shaded region represents the 95% confidence interval. Data from HI individuals are shown in various colors [see audiograms, Figure 1]. Open symbols show all binned data and closed symbols, only points with post-binning SNR of 6 dB
