BILATERAL COCHLEAR IMPLANTS: RESTORING BINAURAL PROCESSING BY EXPERIENCE AND TRAINING WITH BINAURAL CUES

Grant number: 1081478 | Funding period: 2015 - 2018

Completed

Abstract

Cochlear implantation in both ears is increasingly common and while there are benefits, performance falls short of expectations, likely due to the degradation of the long-term deaf brain’s sensitivity to small timing differences of sounds reaching each of the two ears. By confirming the hypothesis that experience with high-fidelity timing information will improve performance, this study will drive the technical innovations required to maximise the benefits and investment of bilateral implants.
