This is the new home of the former web site CorticalERA.com
This is a non-profit educational & technical resource for Audiologists to promote the development, availability and clinical use of Cortical evoked response audiometry (Cortical Auditory Evoked Potentials, CAEPs), a technique for objective hearing threshold estimation based on the "N1-P2" response.
The impetus for creating these pages was to:
inform the international audiological community of the benefits and limitations of Cortical ERA;
compensate for some misinformation on, or ignorance of, this subject in the literature;
showcase a system designed by the author of the site to demonstrate how Cortical ERA can be implemented to produce a user-friendly, fast and efficient test.
generate sufficient user demand to persuade equipment manufacturers to make an efficient version of this test available on their evoked potential systems.
