Figure 6. Model-based average absolute difference between children in DPOAE-level decrement per year of life.

Figure 6.

The average absolute difference in the age effect on DPOAE level between children given by f2. Units are dB SPL per year of life. The small average absolute difference in the age effect on DPOAE level between children in the sample indicates a consistent maturational effect at most f2 frequencies. The estimated age effect is variable at an f2 of 1.5 kHz, but is otherwise highly consistent across children.
