초록
This study investigates the differences in nasalance across handicap, gender, and vowels for the group of profound hearing-impaired children, as well as the correlation between nasal energy and oral energy which are used to compute nasalance. Three groups of children were recruited for this study: 18 children with cochlear implants(CI), 18 children with hearing aids(HA), and 18 children with normal hearing(NH) as a control group. The subjects were asked to read 7 Korean vowels(/ɑ, ʌ, o, u, ɯ, i, ɛ/). Results showed that there is a significant difference in nasalance across handicap, gender, and vowels. In particular, CI group has a significantly higher nasalance than NH or HA, and HA group has a significantly lower nasalance than NH. And there is a significant positive correlation between nasal energy and oral energy for the normal hearing group.
