The purpose of this study was to examine the changes of acoustic characteristics of hearing impaired children's sound and speech before and after offering auditory feedback. which used a hearing aid and a cochlear implant, and to find out the effects of auditory feedback on the changes. The participants were composed of 10 normal children, 10 children with a hearing aid on, and 10 children with a cochlear implant on. The conditions for the selection of participants were limited to children with no physical handicaps including hearing impairment, children .who lost hearing before language acquisition, children whose hearing loss was over 90 dB, and children who depended entirely on a hearing aid. Their age range was from 9 to 10 years old. In order to find out the changes of acoustic characteristics of hearing impaired children's sound and a cochlear implant made by auditory feedback., the study went through F1, F2, F2-F1 analyses in the sounds of /ah, uh, ih/ vowels through CSL, and compared them with a F0 analysis in the first and second syllabus speeches. The mean differences of F0, F1, F2, F2-F1, before and after putting on a hearing aid and a cochlear implant, were verified by means of a paired t-test. To compare the means of F0, F1, F2, F2-F1 between the group of a hearing aid and the group of a cochlear implant, a t-test was conducted. The results of this study were as follows; First, auditory feedback through the use of a hearing aid and a cochlear implant improves artimlation problem in the sounds of /ah, uh, ih/ vowels created by hearing impaired children. That is, after the auditory feedback, the location of tongue was modified by putting lower or bad<.ward their tongue for /ah/ vowel, higher or more backward for /uh/ vowel, and higher or more forward for /ih/ vowel. Since this phenomenon is considered to improve the articulation of well problem through the modification of the location of tongue by offering auditory feedback, there can be direct correlations between auditory feedback and acoustic characteristics of sound. Second, auditory feedback through the use of a hearing aid and a cochlear implant improves articulation problem in the healing impaired children's first and second syllabus speeches. That is, since the fact that the pitch gets lower means the improvement of artimlation problem, there can be direct correlations between auditory feedback and acoustic characteristics of speech. Finally, the types of auditory assistants offering auditory feedback do not influence the improvement of articulation problem in the sound and speech. That is, since no differences are shown between the group of a hearing aid and the group of a cochlear implant offering auditory feedback, the existence of auditory feedback can be more important for the improvement.
