About The Book

Like other volumes in the Core Clinical Concepts in Audiology SeriesSpeech Audiometry is designed to be particularly helpful and appealing to students and clinicians. It provides a single, easy to manage volume that provides broad coverage of speech audiometry and masking in clinical protocols. In addition to providing appropriate background information, the coverage presents a broad spectrum of assessment tools ranging from traditional to modern. Procedures in this book will assist clinicians in determining differential diagnosis, assessing auditory processing ability, identifying pseudohypacusis, determining cochlear implant candidacy, predicting hearing aid benefit, and counseling.

Douglas L. Beck, AuD, speaks with Dr. Lawson about his textbook on speech audiometry, critical differences in word recognition scores, dynamic range of speech, and more. Read the article from The Hearing Review here.

About The Authors

Gary D. Lawson, PhD, is a Professor and coordinator of the AuD program in the Department of Speech Pathology and Audiology at Western Michigan University. After earning a bachelor’s degree at the University of Tennessee, he served in the United States Army and then worked as a television director. He earned a master’s degree at the University of Tennessee and a Ph.D. at Michigan State University. Professor Lawson has worked at three universities and in a public school system. He has worked at Western for over 30 years. His experiences include academic and clinical teaching, coordination of clinical services and practicum, participation in clinical research in a grant funded program for hearing impaired children, provision of audiologic services, and consulting in a variety of settings. Aside from speech audiometry his current professional interests include hearing loss prevention for those working in noisy environments, the use of audition in independent travel by those with blindness or low vision, and speech perception by those with hearing loss. He enjoys being around students and having a physically active life style when not at work.v

Dr. Peterson is an audiologist with 23 years of clinical experience in a variety of clinical settings. She received her master’s degree in 1986 and her doctor of audiology degree in 2007.

She joined the clinical faculty at Western Michigan University in 2005, where she teaches courses in geriatric and rehabilitative audiology and in cochlear implants in the Doctor of Audiology program. She also works with students in their clinical experience in the audiology clinic at the university. Dr. Peterson continues to be actively involved in the dispensing of hearing aids, evaluation of individuals with auditory processing disorders, and rehabilitation of individuals with hearing loss, including cochlear implant recipients.
