Abstract
ABSTRACT Despite much research focusing on hearing aid and cochlearimplant devices, their engineering, and how they might be modified toensurebetteruse,researchstillcannotfullyexplainwhytwoindividualswiththe same configuration of hearing loss demonstrate significantly differentimprovements in speech understanding with similar hearing devices. Onepotential source of performance variability might be the central auditorysystem. Here we review the use of speech-evoked cortical potentials toinvestigate issues of performance variability and auditory rehabilitation.Specifically addressed are issues pertaining to the neural detection of time-varying speech cues, auditory training, and aging. KEYWORDS: Auditory evoked potentials, neural plasticity, hearing aidacclimatization, cochlear implants, auditory training, auditoryrehabilitation Learning Outcomes: As a result of this activity, the reader will be able to (1) describe how hearing involves bothperipheral and central mechanisms and that hearing loss (as well as the reintroduction of sound) alters centralauditory function, and (2) explain that the aforementioned experience-related biological changes probablycontribute to a person’s ability to make use of a hearing aid or cochlear implant.
