Wavelet Analysis for Audiologists

Wavelets and wavelet analysis represent a significant advance in our ability to record and analyse auditory evoked potentials (AEPs). Obtaining knowledge about this growing area can be difficult, however, as existing wavelet reviews are typically entrenched in mathematical theory. This paper provides the first practical wavelet review written for the clinical audiologist. Specifically, the paper will answer the question “what is a wavelet”, describe continuous and discrete wavelet analyses, describe four of the most promising applications of AEP wavelet analysis, review AEP wavelet research conducted to date, and comment on AEP wavelet applications for the future. It is hoped this review will give audiologists a better understanding of current AEP wavelet research, and prepare them for the clinical implications that will follow.
