Electronic Thesis and Dissertation Repository
This thesis aimed to explore the applicability of Cortical Auditory Evoked Potentials (CAEPs) and Envelope Following Responses (EFRs) as objective aided outcome measures for use in infants wearing hearing aids. The goals for CAEP-related projects were to evaluate the effect of speech stimulus source on CAEPs, non-linear hearing aid processing on tone-evoked CAEPs, and the effect of inter-stimulus intervals on non-linear hearing aid processing of phonemes. Results illustrated larger amplitude CAEPs with shorter latencies for speech stimuli from word-medial positions than word-initial positions, and no significant effect of the tone burst onset overshoot due to non-linear hearing aid processing. Inter-stimulus …
