The tests were believed to be linked to the availability of Temporal Fine Structure (TFS) cues. 20 profoundly deaf children with CI (5-17years) and 31 NH peers participated in the study. Harmonic Intonation (HI) and Disharmonic Intonation (DI) tests were used to measure low-frequency pitch perception. HI/DI outcomes were found poorer in children with CI. CI and NH groups showed a statistically significant difference (p<0.001). HI scores were better than those of DI test (p<0.001). Chronological age had a significant effect on DI performance in NH group (p<0.05); children under the age of 8.5years showed larger inter-subject-variability; however, the majority of NH children showed outcomes that were considered normal at adult-level. For the DI test, bimodal listeners had better performance than when listening with CI alone. HI/DI tests were applicable as clinical tools in the pediatric population. The majority of CI users showed abnormal outcomes on both tests confirming poor TFS processing in the hearing-impaired population. Findings indicated that the DI test provided more differential low-frequency pitch perception outcomes in that it reflected phase locking and TFS processing capacities of the ear, whereas HI test provided information of its place coding capacity as well.
