PURPOSE: The objective of the study was to investigate the influence of bimodal stimulation upon hearing ability for speech recognition in the presence of a single competing talker. METHOD: Speech recognition was measured in three listening conditions: hearing aid alone (HA); cochlear implant alone (CI) and both devices together (CI + HA). To examine the use of low-frequency cues the competing masker voice was manipulated with respect to fundamental frequency (F0) and formant frequencies (F(n)). Twelve implanted adults were included in the study. RESULTS: Group results revealed only a relatively small benefit of CI + HA compared to the CI alone. A detailed analysis of errors which was assumed to be an indicator for the release from masking revealed that this benefit was not attributed to improved target-masker segregation. The variable determined to be responsible for segregating target and masker talkers was a large difference in F0 of the voices. This held true for all, CI alone, HA alone and CI + HA listening conditions. CONCLUSIONS: Bimodal hearing improved overall speech recognition of both the target and the masker. No evidence for better target-masker separation with bimodal fitting could be found. |
