title: Reliability and validity of late vertex-evoked response audiometry.
abstract: In order to evaluate the current visual scoring technique in the late vertex-evoked response audiometry (ERA), the detectability of the response, errors in judgment, consistency between scorers and test-retest reliability were studied in adults and young children in waking and sleeping states. In waking adults, ERA proved to be a quite reliable and valid method for testing hearing objectively. On the contrary, a marked inconsistency was found in the appearance of the response in children during sleep. From a clinical standpoint, ERA in waking adults and sleeping children should be regarded as two substantially different methods.
