Like other books in the Core Clinical Concepts in Audiology Series, Speech 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.

Speech Audiometry, Word Recognition, and Binomial Variables: Interview with Gary Lawson, PhD
Douglas L. Beck, AuD, speaks with Dr. Lawson about his 2011 textbook on speech audiometry, critical differences in word recognition scores, dynamic range of speech, and more.
