Objectives: To explore binaural speech perception patterns in hearing aid (HA) and/or cochlear implant (CI) users through a retrospective observational study.Design: Monaural and binaural speech perception scores of 83 bimodal CI+HA, 89 bilateral CI, and 82 bilateral HA users were analyzed.The binaural benefit pattern dominated at 55% in the bilateral HA group, while only 1% of the binaural interference pattern was observed. The binaural benefit pattern was similarly dominant for both CI groups (bimodal CI+HA: 37%; bilateral CI: 40%); however, the bilateral CI group exhibited a higher rate of binaural interference than the bimodal CI+HA group (bimodal CI+HA: 8%; bilateral CI: 12%).The presence of binaural interference implies that listening on two devices is not always better than one. Increased understanding of how this binaural disadvantage affects speech perception for hearing-impaired users is clinically essential for future design of training-and device-based rehabilitative strategies to increase the binaural benefits.
