PurposeThe purpose of the study was to evaluate the contribution of acoustic hearing to the perception of suprasegmental features by adults who use a cochlear implant (CI) and a hearing aid (HA) in opposite ears.

Method23 adults participated in this study. Perception of suprasegmental features—intonation, syllable stress, and word emphasis—was assessed. All tests were administered in 2 conditions: CI alone and CI + HA (bimodal).

ResultsScores were significantly higher in the bimodal condition in comparison to scores in CI alone for all 3 tests. In both conditions, there was great variability among the individual participants. Significant negative correlations emerged between perception of suprasegmental features and the unaided pure-tone average of the contralateral ear to the CI.

ConclusionsThis study found a significant bimodal advantage for perception of all suprasegmental features, most probably due to the better low-frequency acoustic hearing that is provided by the HA. Outcomes suggest that in cases of residual hearing in the contralateral ear to the implanted ear, HA use should be encouraged.
