- Abstract
Pitch perceptionis the most important factor in perception of phonetic and prosodic features of speech. The difference limen for frequency (DLF) is the index of ability to percept the pitch. The purpose of this study was to examine the ability of people with cochlear implant in pitch perception at the frequencies of 500, 1000, 2000 and 4000 Hz and to compare it with normal healthy counterparts. In this cross-sectional study, DLF test was conducted on 17 normal individuals with an average age of 32.76 ± 6.5 years old and 9 individuals with cochlear implant with an average age of 31.77 ± 6.6 years old who had hearing loss after speech training. After a period of speech training (on average 8 sessions), DLF test was repeated for people with cochlear implant. Data were analyzed with statistical package SPSS using Paired t-test and independent variables tests. In the initial test, the DLF in individuals with cochlear implant in all experimental frequencies was significantly higher than normal people (p <0.05). Considerable improvement was observed in the level of difference limen for frequency of people with cochlear implant after training course (p <0.05).The findings of this study show that people with cochlear implant have partially ability to understand the pitch, especially at low frequencies and this ability improves with regular training.
