디지털 음성변환이 청각장애아동의 어음변별력 향상에 미치는 효과 = The Effectiveness on Speech Discrimination Ability for the Hearing Impaired with Digital Speech Transformation

다국어 초록 (Multilingual Abstract)

Advances in hearing aid technology are increasing greatly the sophistication of hearing aids and of techniques for accurate measurement. However, although the development of hearing aid technology, the speech discrimination ability for hearing impaired is lagged far behind to understand in education situation. The purpose of this study was to illustrate the effectiveness of the speech discrimination according to three different electroacoustic inputs which are equal 12dB amplification in all speech words including consonant and vowel, 12dB amplification in above 2000Hz frequencies, and 12dB amplification in target noun. The three different speech words which were input are one syllable consonant itself, and two different or same consonants, and one and two syllable vocabularies. Thirty hearing impaired who were in the degree of severe hearing loss with sensorineural hearing loss were participated for this study. The results of this study were that the 12dB amplification in 2000Hz was most effective in three different speech words discrimination than those of the two different electroacoustic situations. Therefore, this study suggested that the method of 12dB amplification above 2000Hz is most effective to teach speech discrimination abilities for hearing impaired.
