This study examines the developmental effects on two types of cortical auditory evoked potentials: the P1-N1-P2 complex (onset response), related to sound detection, and the acoustic change complex (ACC), related to sound discrimination. The aim was to document these effects in normal hearing (NH) listeners and cochlear implant (CI) users in quiet and noisy (+10 dB SNR) listening conditions. Participants included 91 children and 11 young adults with normal hearing, and 59 CI users (48 prelingually deafened children and young adults, and 11 post-lingually deafened adults). In both listening groups, results indicated similar developmental patterns for both onset and ACC responses, with the ACC maturing later and being more affected by noise. The findings also suggest that CIs support typical development of cortical responses, although CI users face challenges in noisy environments. These cortical auditory evoked potentials can help document the central auditory system's development and estimate behavioral performance in CI users.
