Table 1.
Mean and standard deviation (SD) of knot frequencies and slope values (cycles/kHz) for spline modeling on DPOAE phase-frequency functions. The suppressor conditions are represented in the four columns. Standard deviations are encased in brackets below the corresponding mean. LF = Low frequency; HF = High frequency.

| Knot frequency (Hz) | 1356 | 1311 | 1367 | 1382 |
| SD | [196] | [160] | [200] | [200] |
| LF slope (cycles/kHz) | −1.98 | −1.96 | −1.97 | −1.92 |
| SD | [0.33] | [0.35] | [0.36] | [0.35] |
| HF slope (cycles/kHz) | −0.20 | −0.22 | −0.21 | −0.20 |
