A Volume in the Core Clinical Concepts in Audiology Series

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.


"I found the book to be well-laid-out in clear chapters that followed a logical sequence. This book is a nice size, so it is easy to hold and to take with you to read anywhere. This is a real bonus when you are a busy clinician who needs to read on the train or the bus. The book has an easy-to-read style, and if there is an area that you are particularly interested in, you can read the individual section and it will still make sense. It is very useful to be able to dip in and out of sections and find the information you are most interested in.
Throughout the book are summary tables which are great for finding facts and literature that you want to remind yourself of without having to look through whole chapters. I would recommend this book to anyone wanting to increase their knowledge of OAE testing."
