An Account of Some Relationships Between Otoacoustic Emissions and the Olivocochlear Bundle

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…

Time Compressed Speech

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…
