The cross-check principle in pediatric audiometry.

We discuss a method of pediatric audiologic assessment that employs the "cross-check principle". That is, the results of a single test are cross-checked by an independent test measure. Particularly useful in pediatric evaluations as cross-checks of behavioral test results are impedance audiometry and brain-stem-evoked response audiometry (BSER). We present five cases highlighting the value of the cross-check principle in pediatric audiologic evaluation.
