A Pilot Study on Cortical Auditory Evoked Potentials in Children: Aided CAEPs Reflect Improved High-Frequency Audibility with Frequency Compression Hearing Aid Technology

Table 1

Summary of electroacoustic verification results for all HI cases (1 through 5). Summaries are shown across stimuli (2 kHz and 4 kHz tone bursts) and hearing aid conditions (NLFC enabled and no-NLFC). Results are compared to the corresponding cortical auditory evoked potentials (CAEP) judged as present or absent per condition.
