摘要: Electric hearing is presently the only treatment solution for patients with profound-to-severe loss. For those also preserving low-frequency residual on ipsilateral ear, combined electric-and-acoustic stimulation (EAS) could notably improve their speech understanding abilities relative to aided electric-only (E-only) hearing. Early behavioral studies have consistently shown advantage of stimulation. The aim this work was objectively examine over using an oddballparadigm based event-related potential (ERP) experiment. vowel stimulus processed by vocoding processes simulating E-only and EAS conditions, generated stimuli were presented normal-hearing listeners in ERP Experiment results showed that mismatch negativity (MMN) response elicited combined-stimulation condition featured a smaller peak amplitude more delayed latency than condition. MMN demonstrated compared condition, combinedstimulation much closer full-spectrum stimulus, yielding neurophysiological evidence advantage.
