Background.
This study investigated whether cortical auditory evoked potentials (CAEPs) could reliably be recorded and interpreted using clinical testing equipment, to assess the effects of hearing aid technology on the CAEP.
Methods.
Fifteen normal hearing (NH) and five hearing impaired (HI) children were included in the study.
NH children were tested unaided; HI children were tested while wearing hearing aids.
CAEPs were evoked with tone bursts presented at a suprathreshold level.
Presence/absence of CAEPs was established based on agreement between two independent raters.
Results.
Present waveforms were interpreted for most NH listeners and all HI listeners, when stimuli were measured to be at an audible level.
The younger NH children were found to have significantly different waveform morphology, compared to the older children, with grand averaged waveforms differing in the later part of the time window (the N2 response).
Results suggest that in some children, frequency compression hearing aid processing improved audibility of specific frequencies, leading to increased rates of detectable cortical responses in HI children.
Conclusions.
These findings provide support for the use of CAEPs in measuring hearing aid benefit.
Further research is needed to validate aided results across a larger group of HI participants and with speech-based stimuli.
