Volume 1, Chapter 01: Current and Emerging Clinical Applications of the Auditory Steady State Response (ASSR)


The chapter provides an up-to-date review of evidence-based clinical applications of the auditory steady state response (ASSR), and research findings on emerging applications of ASSR. The chapter begins with a discussion of brief overview of information necessary for measurement and analysis of the ASSR in a clinical setting, including the anatomical and physiological bases of the ASSR. Instrumentation for recording and automated analysis of test results, and non-pathological factors influencing the ASSR. The remainder of the chapter is devoted to a summary of research supported current clinical applications of ASSR among them estimation of auditory thresholds in infants and young children with severe-to-profound sensory hearing loss, diagnosis of auditory neuropathy spectrum disorder (ANSD), objective confirmation of hearing status in patients with false or exaggerated hearing loss, and diagnosis of auditory processing disorders in at risk patient populations.
