by Julianne M. Ceruti, Au.D., Ph.D., Leslie Bernstein, Ph.D., and Frank Musiek, Ph.D.   The Decrement in Noise Test (DeNT) is a clinically oriented procedure modeled after the GIN test that employs both partially filled gaps (i.e., decrements) and full gaps. This test was developed to improve clinical assessment of temporal resolution that addresses the intensity resolution confound when only

by Frank E. Musiek   Introduction The internal auditory meatus (IAM) is a canal in the temporal bone that extends from the bony cochlea medially to an opening in the posterior aspect of the petrous portion of the temporal bone. This structure is germane to audiologists because it contains three nerves of interest to audiologists: 1- the auditory nerve, 2-

Musiek, PhD, and Jeffrey Weihing, PhD   There is general scientific agreement on the definition, diagnosis, and treatment of CAPD Central auditory processing disorder (CAPD) is a complex and evolving subject, but remains a solid diagnostic entity.

Frank Musiek     Introduction   Back in the 1950’s Ettore Bocca and his Italian colleagues (Bocca, Calearo, Cassinari, 1954) were the first to develop and make significant clinical use of central auditory tests. They had learned that the pure tone audiogram was not useful in reflecting deficits of the central auditory nervous system (CANS). They then proceeded to develop

Aaron Whiteley   The focused examination of otoacoustic emissions began in the 1940s with Georg von Bekesy. Inspired, yet unconvinced by Helmholtz’ idea that the cochlea consisted of resonant structures, Bekesy developed an intricate method of examination that would lead to the place theory and traveling wave theory (Hall, 2000). Bekesy’s experiments built the foundation for a common understanding that

Frank E. Musiek   There is no question that considerable research has been conducted on the cochlear nucleus in recent years. Anatomists, physiologists, psycho-acousticians, audiologists and others have made contributions to our understanding of the CNu. However, in reflection on some current research of the CNu I kept thinking about some very early research which was clinical in nature that

Elissa H. Kawamoto, B.S. Graduate Student, Department of Speech, Language and Hearing Science, University of Arizona   In order to develop strong diagnostic and clinical skills, one must have a deep understanding of the anatomy and physiology of the entire system related to ones field of study. Considerable attention must be directed towards understanding the region where vestibular schwannomas grow. This is

Herbert Jay Gould, Ph.D. School of Communication Sciences and Disorders, The University of Memphis   Compressed speech has been studied since the early 1950s (Garvey 1953) and has been suggested as a tool for the diagnosis of APD since at least 1977 (Beasley and Freeman 1977). The general consensus is that abnormal performance on compressed speech material reflects a deficit in

By Mike Webb   The goose is dead…or at least partially cooked.  I use this metaphor, of course, as the goose who laid the golden eggs: in our audiology context, the “hearing aid” goose.  I, for one, believe it may be a positive, pivotal moment for strengthening the field of audiology. A similar pivotal moment occurred in 1978 for audiology
