Full Description
Otoacoustic emissions now play an important role in hearing screening and the clinical assessment of children and adults. However, a new wave of evidence is challenging our fundamental understanding regarding OAE sources and mechanisms. Similarly, just as we have settled on methods and protocols for clinical uses of otoacoustic emissions, ongoing research suggests new opportunities for evidence-based clinical applications. In Otoacoustic Emissions: Principles, Procedures, and Protocols, Drs. Dhar and Hall have collected 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 material covered in the book is appropriate for intermediate and advanced students, and ideal for practitioners. With a consistent focus on practical information needed by the clinical audiologist, and a eye to future developments, authors Dhar and Hall systematically raise and answer questions necessary for a thorough understanding of OAEs, and an appreciation of their clinical value.
