Abstract
In recent years, cortical auditory evoked potential (CAEP) testing has emerged as a reliable technique to assess young infants’ access to speech sounds via their hearing aids. There are numerous sets of stimuli available which can be used to perform aided CAEP testing, each with its unique advantages and limitations resulting in differing clinical implications. Understanding the characteristics of each of these stimuli sets is important to enable clinicians to make informed decisions regarding their clinical utility. In this presentation, the differences in the origin and generation of CAEP stimuli will be explored. This will be followed by a discussion on the frequency specificity of each set of stimuli and the clinical risks associated with this will be considered. Lastly, the individual calibration principles for each stimulus set will be explained and compared against the long term average speech spectrum to determine if they mimic true representations of speech across the frequency range. Case study examples will be used to demonstrate the clinical implications of using these stimuli and their relevance to the infant hearing aid user population.
