Audiology: Science to Practice

With two new chapters, improved artwork, and significant updates made throughout to increase readability, the fourth edition of Audiology: Science to Practice continues to be the most comprehensive textbook for audiology and hearing science courses, as well as for health care professionals wanting a better understanding of hearing science and audiology practices. It is written in a style that makes new or difficult concepts relatively easy to understand, while still providing more coverage of hearing and vestibular science and clinical audiology than other introductory texts. Topics include information about the profession of audiology, acoustics, anatomy and physiology of the auditory and vestibular systems, preparing for the patient, otoscopy, pure-tone audiometry and speech measures, audiogram interpretations, masking, tympanometry, acoustic reflexes, wideband acoustic immittance, otoacoustic emissions, auditory brainstem responses, hearing screening, hearing aids, assistive listening aides, cochlear and other implantable devices, vestibular evaluation, descriptions of auditory and vestibular disorders, and aural rehabilitation. There is also a chapter on the roles of speech-language pathologists related to understanding and caring for persons with hearing and balance concerns. Where relevant, the material includes evidence-based practice. New to the Fourth Edition Two new chapters: Role of the Speech-Language Pathologist and Other Treatments and (Re)habilitation of Hearing and Balance Disorders Many new beautifully drawn two-color anatomy and physiology illustrations Black and white figures have been color-enhanced Several chapters were reorganized and updated to include vestibular anatomy, physiology, and vestibular disorders within the relevant auditory chapters A separate chapter on vestibular evaluation and bedside screening Many chapters expanded to provide information on environmental factors that affect the transmission of sound, signal-to-noise ratio, preparation for testing, cerumen management, assistive listening technology systems (HATS), and status of over-the-counter hearing aids Updated references and standards throughout Key Features Many illustrations than other texts to help clarify and expand on key concepts Chapters begin with a list of learning objectives and end with key references Punctuated with historical and informational side boxes An easy-to-read writing style to help students understand scientific concepts Key terms highlighted throughout with a comprehensive end-of-book glossary A PluralPlus companion website with PowerPoint lecture slides and an image bank for instructors, James Jerger's chapter on the History of Audiology, and more The authors have also created a companion study aid for students, Audiology Workbook, Fourth Edition.

Steven Kramer, PhD>, is Professor in the School of Speech, Language, and Hearing Sciences at San Diego State University, where he has been a faculty member and administrator since 1985. He served as the department chair from 1990 to 2001 and as the Codirector of the Audiology Doctoral (AuD) Program, offered jointly by San Diego State University (SDSU) and the University California San Diego (UCSD), from 2003 to 2016. He obtained his master's and doctoral degrees in audiology and hearing science from the University of Florida. He was a licensed and certified audiologist for about 40 years. Before his appointment at SDSU, he was a clinical faculty member at the University of Texas Medical Branch in Galveston, Texas. He has taught a wide array of courses at the graduate and undergraduate levels, including hearing science, diagnostics, medical audiology, evoked potentials, and psychoacoustics.+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++David K. Brown, PhD, has been Professor in the School of Audiology at Pacific University since it enrolled its first students in 2012.
