고심도의 청각장애를 가진 아동의 음성은 높은 음도와 강도, 과비음 등 건청 아동과는 매우 다른 특성을 나타낸다. 그 중에서 초분절적인 요소에 속하는 억양은 청각장애 아동의 경우 단조롭고 높낮이 변화가 크지 않아서 의미전달에 어려움을 주는 중요한 요소이다. 청력손실이 고심도인 경우 수술을 하게 되면 청각적 수용능력을 높일 수 있어, 최근 부각되고 있는 인공 와우 이식수술을 받은 아동 또한 이러한 억양에서의 문제는 완전히 해결 받지 못하고 있다. 따라서 이 연구에서는 인공 와우 이식수술을 받은 청각장애 아동이 건청 아동과 억양에서 어떠한 차이를 드러내는지에 대해 알아보고자 하였다.

Recently, the number of those who were transplanted cochlear implants increased as health insurance increases has expanded. Last six years between 2005 to 2009, patients who received a cochlear implant surgery were about 3,300 and number of cochlear implants in adults of them have shown growing aspects. In the case of young children, they actively participated auditory training program after cochlear implant surgery and the studies related to auditory training in child are many, but the studies related to auditory training in adults is insufficient. In this study, we perform the auditory training for the female adult (age 54) received cochlear implant after language acquisition used Ling 6 sounds test, standardized consonants, vowels and sentences listening test and word recognition and confirmation test. As a result after auditory training for 10 weeks, she identified all phonemes in Ling 6 sound test and performed close to 100% in standardized consonants, vowels and sentences listening tests. Also, she improved the ability of real-world environmental sound and real-world words identifications by 57-95%. The results of this study showed the need of auditory training program with systematic and effective planning and considering the characteristics of the individual for adults.

Objective : This study examined the effects of vestibular sensory integration on the sensory processing, problem behavior, and auditory behavior in children who had cochlear Implants. Methods : This single-subject AB study was conducted for 11 weeks from August to November 2019 with three children with cochlear implants. A pre-test measure of each child's sensory processing and auditory behavior was recorded with the baseline on operationally defined behavioral problems as four incidents during 40 minutes of free play with an occupational therapist. The treatment period was 15 40-minute sessions of vestibular sensory integration. Behavioral problems were monitored and recorded during each treatment session. Once treatment was complete, a post-test was conducted on the children's sensory processing and auditory behavior. Results : The sensory processing and auditory behavior of all three participants improved after the vestibular-focused sensory integration, and diverse problem behaviors showed decreasing trends during the interventions. Conclusion : Vestibular sensory integration leads to positive changes in the sensory processing, problem behavior, and auditory behavior of children with cochlear implants.

Among various kinds of hearing aids which have been developed so far. the conventional air conduction hearing aids have some problems such as the acoustic distortion, an howling effect due to acoustic feedback. Another type of hearing aid. the cochlear implant system can be applied to the profound imparied person. However. it shows the disadvantage that there is no possibility of recovery of the acoustic organ such as ossicle. On the other hand. the implantable middle ear heaving device directly vibratos the ossicular chain and has better sound qualify. good cosmetics for appearance. and wide frequency responses so that it can overcome the defects or the conventional hearing aids. In this paper, a mathematical modeling and a momentum equation derivation of the DET has been performed. For the optimization of the structure dimension generating maximal vibrating force of the DET. the computer simulation using a finite element analysis (FEA) software has been performed. Also. the vibrating transducer has been designed to make the frequency characteristics or the transducer be similar to those of the normal middle ear. Through the experimental results, the measured vibration characteristics of the DET has been evaluated to verify the performance for the application to implantable middle ear hearing devices.
