Otoacoustic Emissions: Principles, Procedures, and Protocols, Second Edition is a readable yet comprehensive source of information on otoacoustic emissions (OAEs). OAEs now play an important role in hearing screening and the clinical assessment of children and adults. The text begins with a succinct overview of OAEs and a historical description of their discovery and emergence as a clinical tool.
Otoacoustic Emissions distills in 10 chapters the latest information on OAEs from basic research to clinical applications. The book is concise, but comprehensive, and covers the essentials of the subject from innovative and up-to-date perspectives. The second edition features updates across all chapters, including current research findings and changing perspectives on OAE taxonomy. Important information is highlighted with new and updated illustrations throughout the book.
The material covered in the book is appropriate for intermediate and advanced students, and ideal for practicing audiologists. With a focus on practical information needed by the clinical audiologist and an eye to technological developments, authors Dhar and Hall provide an up-to-date, straightforward, and clinically focused source of information on OAEs.

About The Authors
Sumitrajit Dhar, PhD, is Professor of Audiology and Hearing Science and Chair of the Roxelyn and Richard Pepper Department of Communication Sciences and Disorders at Northwestern University in Evanston, Illinois. Sumit studied at the University of Mumbai, Utah State University, and Purdue University. At Northwestern University, Sumit teaches courses in the science and practice of audiology. His laboratory works on the origin and propagation of otoacoustic emissions, their clinical applications, and their modulation by the efferent neural network. More recently, his laboratory has also started working on hearing health care design and delivery. Work in Sumit's laboratory has been funded continuously by the National Institutes of Health since 2003. He has also received funding from various foundations and private agencies such as the Knowles Hearing Center, Starkey, American Hearing Research Foundation, American Speech-Language-Hearing Foundation, and Deafness Research Foundation.
James W. Hall III, PhD, is an internationally recognized audiologist with 40 years of clinical, teaching, research, and administrative experience. He received a bachelor's degree in biology from American International College, a master's degree in speech pathology from Northwestern University, and his PhD in audiology from Baylor College of Medicine under the direction of James Jerger.
During his career, Dr. Hall has held clinical and academic audiology positions at major medical centers. He is the recipient of numerous professional awards, including the American Academy of Audiology Career Development Award and the AAA Presidential Award. Dr. Hall now holds academic appointments as professor (part-time) at Salus University and the University of Hawaii, numerous adjunct and visiting professor positions, and also Extraordinary Professor at the University of Pretoria in South Africa. He's also president of James W. Hall III Audiology Consulting LLC.
Dr. Hall's major clinical, research, and teaching interests are clinical electrophysiology, auditory processing disorders, tinnitus, hyperacusis, and audiology applications of tele-health. He is available for instruction of Doctor of Audiology students, continuing education of audiologists and physicians, consultation regarding audiology services and procedures, and service as an expert witness. Dr. Hall is the author of over 150 peer-reviewed journal articles, monographs, or book chapters, and nine textbooks including the 2014 Introduction to Audiology Today and the 2015 eHandbook of Auditory Evoked Responses.
