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.
