Effects of Amplification on Cortical Electrophysiological Function

There has been great interest in using speech-evoked cortical auditory evoked potentials (CAEP) as an objective hearing aid validation measure, because CAEPs allow us to assess the audibility of speech sounds at the highest (cortical) levels. Here is a review by Sridhar Krishnamurti and Larry Wise, as well as results from a study they conducted that suggests there is clinical value of CAEPs for assessing cortical changes from amplification, as well as using this data in audiology services to demonstrate patient benefit.
