ABSTRACT

Objective：The purpose of this study was to document word discrimination abilities by aided thresholds in children who use a cochlear implant in one ear and a hearing aid in the other ear. Method：Twenty-one children participated in this study. All children used a cochlear implant and a hearing aid which was fitted using the NAL-NL1 prescription. Performance in word discrimination was assessed under four noise conditions (N/O, N/F, N/CI, N/HA) and three aided conditions (CI, HA, CI/HA). Results：The group of CI aided threshold below 30 dBHL is higher than other groups of CI aided threshold over 30 dBHL in word discrimination scores under monaural conditions with CI. The group of HA aided threshold below 50 dBHL is higher than other groups of CI aided threshold over 50 dBHL in word discrimination scores under monaural conditions with HA. The group of the highest word discrimination scores is CI aided threshold below 30 dBHL and HA aided threshold 41-50 dBHL under binaural conditions with CIHA and four noise conditions. Pearson correlation is higher HA adied threshold than CI aided threshold. Conclusion：We have shown that the group of CI aided threshold below 30 dBHL and the group of HA aided threshold 41-50 dBHL are higher than other groups in word discrimination scores under four noise conditions (N/O, N/F, N/CI, N/HA) and three aided conditions (CI, HA, CI/HA). Therefore, it is recommended that bimodal stimulation with CI and HA should be fitted by aided thresholds for clinical management of children and adults who wear unilateral cochlear implants.
