My research that utilized Transient-Evoked Otoacoustic Emissions (TEOAE) measurements required the development of novel techniques that, unexpectedly, lead to the discovery that packets of energy that can occur much earlier in time than anticipated. While these early-latency components were not visible using older measurement techniques, others have followed up on our discovery and our field is starting to understand their role in theories of OAE generation and the mechanical cochlear processes underlying them. An important thrust of my research has been to empirically elucidate where in the cochlea these early components are generated and what the generation mechanism is. Most approaches involve signal processing of non-invasive measurements from the ear. However, an apex-to-base cochlear perfusion technique used in Dr. Lichtenhan’s laboratory (at the University of South Florida) has enabled us directly identify the spatial origins of short latency TEOAEs along the cochlear length.
