By: Frank Musiek The dichotic difference score (DDS) has been utilized periodically over the history of dichotic listening. It represents an interesting manipulation of dichotics and relates to its various applications. The DDS simply requires the computation of the differences on performance of dichotic listening between the right and left ears. Generally, this means that if the right ear score

by Frank E. Musiek, PhD A popular discussion for some time has been why can’t children under 7 years of age be tested for CAPD? Many audiologists and speech pathologists argue that much could be done for these children if only a diagnosis of CAPD could be rendered at an earlier age. This is certainly a worthy concept with which

Acquired hearing loss can negatively affect mental health, participation in interpersonal relations, and health-related quality of life. Population-based

[A preview of a the presentation at Pathways for AAA by Deborah Moncrief] Amblyaudia is a deficit in binaural integration, a process that begins with excitatory and inhibitory activation in the medial and lateral superior olivary complexes of the auditory brainstem (Tollin, 2003).  Interaural timing and intensity differences are used to detect coincident signals and to prioritize neural codes for

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
