REVIEWER: E. Kimberly Barry, AuD, Department of Veterans Affairs
SYNOPSIS: This is the fifth edition of a classic audiology text, first published in 1972, which provides a comprehensive overview of the audiologist's scope of practice. This edition has been completely revised and covers a wide range of topics with contributions from over 50 experts. The 41 chapters are divided into five sections which include an introduction to audiology, behavioral tests, physiological tests, special populations, and the management of hearing disorders. The Handbook, commonly referred to as "The Katz Book," not only serves as a leading textbook for audiology students, but also as an authoritative reference for clinical audiologists.
REVIEW: The Handbook is divided into five sections. In the first section, Katz provides an introduction to audiology, which includes a history of audiology and a description of recent changes in the field. Chapter two contains an overview of the anatomy and physiology of the auditory system, as well as a description of congenital and acquired disorders of the ear. Also included within the first section are chapters on the psychoacoustic basis of audiology and the calibration of puretone, noise, and speech signals.
Section II, "Behavioral Tests", opens with a chapter on procedures for conducting the puretone evaluation. Also included in this section is a review of the various types of transducers used in audiologic testing. The third chapter includes a review of word lists, factors affecting speech scores, and interpretation of speech scores. Within the chapter on masking are helpful practice cases for students learning to mask. Also in this section is an important chapter that describes the integration of the audiologic evaluation with the case history in the clinical decision making process.
Section III, "Physiologic Tests of Auditory and Related Functions", opens with three chapters on immittance measures. The first of these includes a historical look at immittance measures and the underlying principles of immittance. The following two chapters, "Tympanometry" and "The Acoustic Reflex", provide an in-depth review of these procedures and their application in diagnostic audiology. An overview of auditory evoked potentials is included in this section, as well as six chapters that provide detailed information on auditory evoked potentials, from electrocochleography to late cortical potentials, as well as a chapter on intra-operative monitoring. A review of balance disorders includes information on the anatomy and physiology of the balance system as well as procedures used to evaluate and manage balance dysfunction. The final chapter in this section reviews theories underlying the generation of otoacoustic emissions, types and measurement of otoacoustic emissions, and their use in the audiology clinic.
Section IV, "Special Populations", begins with information regarding newborn/infant screening and follow-up procedures. Identification protocols, for specific age groups and developmental abilities, are discussed. The next four chapters focus on central auditory processing and include test batteries used in the evaluation and diagnosis of central auditory processing disorders, the management of these disorders, and central auditory evaluation of patients with neurologic disorders. An overview of educational audiology is included, with information regarding habilitation and amplification. Audiologic procedures, used in the evaluation of individuals with mental/developmental disabilities, as well as the audiologist's role in the interdisciplinary team are discussed.. A chapter on occupational hearing conservation reviews the impact of noise exposure and OSHA regulations. A review of malingering/pseudohypacusis describes factors underlying the exaggeration of hearing loss, as well as audiometric test procedures used to detect invalid results. The identification and management of hearing loss in older adults is discussed in the final chapter in this section.
Section V, "The Management of Hearing Disorders", is the final section in the Handbook. The first chapter in this section addresses communication strategies and the effects of noise and reverberation on the ability to communicate, as well as a review of assistive devices. The second chapter provides an excellent review of the characteristics of hearing aids and methods to obtain acoustic measurements. The following two chapters describe techniques used to fit and verify hearing aids in pediatric and adult populations. An overview of the business end of audiology is also contained within this section. Chapter 39 provides an in-depth review of cochlear implants, evaluation protocols, and the management of patients with implants. The final 2 chapters review management options for children and adults with hearing loss.
CRITIQUE: The editor, associate editors, and contributors provide a considerable amount of expertise on the many topics contained within this book. Case histories, which are provided in almost every chapter, help to clarify the subject matter. Excellent in-depth sections on physiologic testing and the management of hearing disorders make this text a complete reference for both the student and the practicing clinical audiologist. The only suggestion I have would be to consider including a separate chapter on metabolic and genetic hearing disorders in the next edition.
