Figure 1. Average DPOAE amplitude and Bekesy hearing thresholds at 2 kHz as a function of time for fourteen subjects. The first two data points are pre-exposure amplitudes. The remaining data points are post-exposure amplitudes. All amplitudes are normalized relative to the two pre-exposure amplitudes. Error bars (standard error of the mean) are plotted if they are larger than the symbol. Also plotted are the fitted recovery functions. |
