TABLE V.

Parameter values for power-law fits to the TBOAE latency data and amount of variance accounted for by the fits. Approximate uncertainties (i.e., 95% confidence interval) for the parameter values are included. When the TBOAE latency estimates are reliable (frequency-dependent stimulus duration and stimulus duration = 2.83 ms), their frequency and level dependence is similar to that of ABR forward latency. The power-law fits account for at least 82% of the variance in the data.
