Secondary Acoustic Cues of Tone Production by Children with Cochlear Implant: The Influence of Implantation and Hearing Age
This study aims to investigate whether children with CIs could make use of secondary acoustic cues to distinguish Mandarin tones in tone production as normal hearing children. If yes
the effects of implantation age and hearing age of cochlear implant on the use of secondary acoustic cues would also be explored.
Method
2
The duration and intensity of tone production were compared and analyzed in 108 cases of 3~7 years old children with cochlear implants (hearing-impaired group)
108 cases of 3~5 years old normal-hearing children (control group) and 33 adults (control group).
Results
2
The implantation age of cochlear device is the key for children with cochlear implants to contrast Mandarin tone by duration and intensity. Early-implanted (implanted from 0 to 2 years) children could contrast Mandarin tones by these two secondary cues as 4-year-old normal hearing children.
Conclusion
2
Receiving cochlear implants before age 2 is critical for hearing-impaired children to contrast Mandarin tones using duration and intensity cues.
