Cochlear echoes, spontaneous emissions, and some other recent advances in auditory science.

Abstract

This is the second of two tutorials designed as an update on recent advances in auditory science for audiologists, otolaryngologists, and others studying or working in the area of hearing and deafness. This article spans diverse areas from psychophysical measures of audiogram fine structure to physical measurements of the motion of the basilar membrane and to so-called cochlear echoes and acoustic emissions. The review is not comprehensive but it gives an overview of salient points of interest as well as an indication of the current state of knowledge in these areas.
