Abstract：Objective To study influential factors affecting di-syllabic tones in hearing-impaired children. Methods Di-syllabic tones were tested in 120 hearing-impaired children aged 3 to 5 years. Data were collected and analyzed using lo-gistic regression models. Results Age at onset of rehabilitation, duration of rehabilitation,hearing threshold levels obtained with the hearing device and gender showed significant influences on di-syllabic tone performance (P<0.05),and the first three factors were predictors for di-syllabic tone performance on logistic regression. Chronological age,type of hearing device and duration of hearing device use didn't show correlation with di-syllabic tone performance (P>0.05). Partition ofχ2 indi-cated that hearing-impaired children who began to receive rehabilitation training before the age of three and continued for more than a year and a half demonstrated better di-syllabic tone performance. Conclusion Properly fitted devices, rehabili-tation training starting before 3 years of age and lasting for at least 1.5 years are of great value in improving di-syllabic tone outcomes in hearing-impaired children.
