Assessing Infant Hearing Using Human Evoked Response Audiometry

Assessing Infant Hearing Using Human Evoked Response Audiometry

Online course

Target Audience:

Clinical audiology learners and graduate students

Course Format: Online - available anytime and anywhere


Beginning with a general introduction to the auditory evoked potentials, this course then emphasizes learning of the auditory brainstem response (ABR) for clinical assessment of infant hearing. Emphasis in the online learning modules is placed on understanding the principles and basic data underlying the procedures for recording, analyzing, and interpreting ABR recordings for clinical audiology. Emphasis in the lab sessions is placed on applying the principles discussed in the learning modules as practical "hands-on" experience with recordings, analyses, and interpretation using the simulated ABR software, called “sABR”.
