성인 난청인을 위한 이야기를 이용한 청능훈련 도구 개발 및 청능훈련 효과에 관한 연구 = Development of a Story Based Auditory Training Tool and Evaluation of the Training Efficacy for Adult Hearing Impaired Listeners

다국어 초록 (Multilingual Abstract)

Purpose: The purpose of this study was to develop lists of stories for the auditory training and to evaluate the effect of 10-week auditory training using developed stories for hearing-impaired listeners. Methods: A total of fifty-five stories and related subjective and objective questions were developed. In order to validate the training materials, thirty-two participants examined the familiarity of stories, the interest of stories, the difficulty of sentences, the familiarity of words and the difficulty of questions. According to the validation results, the stories were revised and recorded by a professional female speaker. For determining the efficacy of auditory training using developed stories, fifteen hearing-impaired listeners participated. Among them, eight subjects (auditory training group) received the 40-minute, once per a week for 10-week auditory training, and seven control subjects (non-training group) did not receive any auditory training. Sentence recognition scores with and without noise and Korean version of international outcome inventory for hearing aids (KIOI-HA) were evaluated at before and after the auditory training. Non-training group underwent the same battery of tests at the same time intervals equivalent to the training group. Results: Results showed that the auditory training enhanced sentence recognition in quiet as well as in noise conditions. Also, there was positive impacts of training on the results of K-IOI-HA. Conclusion: These results suggested that the 10-week auditory training using the stories is useful to improve speech understanding of hearing aid users as well as their subjective satisfaction on hearing aids.
