Abstract

The objective of this presentation is to re-examine the clinical targets for hearing aid recommendation and processing. The main clinical target is the damaged cochlea, and the main measure discussed will be the many patterns of clinical word recognition across level. Study of human temporal bones allows appreciation of the underlying damage to the cochlea in hearing aid cases, with somewhat surprising implications. Primarily, it is necessary to allow for and respond to, a model of depletion of the sensory epithelium (as in macular degeneration). There is an important difference between reverse- engineering the audiology results and providing maximum information to a depleted receptor array. Diagnosis using word recognition, recommendation criteria, and implications for delivering optimal hearing aid output and for studying the results will be discussed.
