This book bridges the gap between theory and clinical application for electro-acoustic and electro-physiologic assessment of hearing loss across the age range. Strategies and techniques for screening and diagnosis of hearing loss are presented clearly and simply. The authors incorporate findings of accumulated clinical experience and recent clinical research in a readable review of electro-acoustic measures (immittance measures and otoacoustic emissions) and electro-physiologic measures (electrocochleography, ABR and ASSR) that are essential for best practice in audiology today. This book is a one-stop resource for clinicians who are responsible for the diagnostic auditory assessment of children and adults.

Douglas L. Beck, AuD, speaks with James W. Hall III, PhD, about his book, Objective Assessment of Hearing (co-authored by De Wet Swanepoel) in The Hearing Review. Read the interview here.


"The book is squarely aimed at providing students with an introduction to the clinical application of objective auditory tests. The authors succeed in providing an in-depth discussion of important concepts, while maintaining a practical focus."
Ryan McCreery, M.S. (Boys Town National Research Hospital), Doody's Review Service (2010)

"... This new text provides a succinct and precise description of the clinical applications of objective assessments. The authors have done an exemplary job explaining why and how an objective assessment tool is used in ordinary clinical settings. Numerous figures and tables are integrated with the text to enhance understanding of the clinical materials by the reader."
Joseph Kei, School of Health and Rehabilitation Sciences, University of Queensland, International Journal of Audiology (2010)

"Objective Assessment of Hearing is an excellent first book in the Electrophysiology component of the Core Clinical Concepts Series. This book is practical and easy reading that students and practitioners will appreciate...this book's focus on clinical learning will be highly appreciated by students and clinicians. Course instructors might need to supplement reading on this topic for advanced scholarship or teaching purposes. The use of color illustrations throughout increases the book's effectiveness. Overall, this is a practical, clinical handbook style text that efficiently provides the most salient information in an appealing format."
Ishara Ramkissoon, Dept of Speech Pathology and Audiology, University of Alabama, Ear & Hearing (2011)

"This text is intended for students, clinicians, and the instructors of audiology programs. The authors write in a style that is easy to read and appropriate for their intended audience . . . provides a succinct and precise description of the clinical applications of objective assessments. The authors have done an exemplary job explaining why and how an objective assessment tool is used in ordinary clinical settings . . . Having read this book, I would agree with the authors that this 186 page book provides contemporary 'pedagogic materials that focus on basic clinical methods and knowledge'. I found this book a useful reference for practicing audiologists too."
—Joseph Kei, International Journal of Audiology (2011)
