The presence of the response or the response characteristic allows us to surmise the subjects’ hearing capability or the performance of their auditory pathways. ERAs are considered an “objective” evaluation because the subject is not required to actively participate in the assessment in many of the tests, unlike various other tests. The short-latency automatic components are favored for threshold estimation, as they are modestly affected by the brain state of the subject. The long-latency components are generally used to surmise the cognitive processing capacity of the brain and are often called event-related potentials (ERPs)1. ERA and auditory-evoked potentials (AEP) are used interchangeably.
