| Popis: | Speech perception in noise is a highly challenging situation experienced by hearing-impaired children (HIC). Despite advances in hearing aid technologies, speech perception in noise still poses challenges. Pitch-based training improves pitch discrimination and speech perception and may facilitate concurrent sound segregation. Considering the role of harmonics in the analysis of concurrent sounds, we performed a harmonic assessment, examined the role of harmonic training in the rehabilitation of moderate-to-severe HIC, and investigated its effect on their speech perception in noise.The participants were 57 normally hearing children (NHC) with a mean age of 7.73 ± 1.57 years and 18 HIC with a mean age of 7.94 ± 1.47 years. The two groups were compared in terms of harmonic assessment, the Pitch Pattern Sequence Test (PPST), the Consonant-Vowel in Noise (CV in noise) test, and the Bamford-Kowal Bench (BKB) test. Subsequently, the HIC underwent harmonic training, and the results of the pre- and post-harmonic training assessments were compared.HIC displayed poorer harmonic discrimination than NHC at all harmonics (P 0.05). They also showed lower scores in PPST, CV in noise, and BKB tests compared to NHC (P 0.05). Harmonic training led to HIC's better performance in harmonic assessment, PPST, and CV in noise test (P 0.05). However, the BKB test results pre- and post-training did not significantly differ (P 0.05).Harmonic training plays a significant role in improving the HIC's temporal processing of the PPST and CV in noise test; therefore, it can serve as a rehabilitation method to enhance temporal processing and auditory scene analysis. |
