Abstract

Hearing loss is one of the most common birth defects among infants. Most of hearing-impaired children are not diagnosed until 1 to 3 years of age - which is too late for the critical period (6 month) for normal speech and language development. If a hearing impairment is identified and treated in its early stage, child's speech and language skills could be comparable to his or her normal-hearing peers. For these reasons, hearing screening at birth and throughout childhood is extremely important. ABR (Auditory brain-stem response) is nowadays one of the most reliable diagnostic tools in the early detection of hearing impairment. In this study, we have developed the system that automatically detects if there is hearing impairment or not for infants or children. For future studies, it will be developed as a portable system to be able to take a measurement not only in sound proof room but also in nursery for neonates.

난청은 가장 흔한 선천성 장애이다. 이 질병의 발생 빈도는 신생아 1000명 출생 당 $1{\sim}3$명 정도로 상당히 높다. 이러한 청력 장애가 조기에 발견된다면 수술적인 치료 등으로 예방할 수 있으나, 그렇지 못할 경우 언어와 학습장애를 초래하게 된다. 이런 관점을 근거로 신생아를 대상으로 한 선천성 난청의 선별검사는 큰 의미를 가지며 난청환자의 조기발견을 위한 노력이 필수적이라 할 수 있다. 기존의 수동 청력검사 시스템은 신생아 청력 평가 시 검사자의 주관성에 의존하게 되므로, 청성뇌간 반응의 뇌파 분석이 잘못될 가능성이 커진다. 따라서 본 연구에서는 난청여부를 자동으로 판독하여 결과를 나오도록 개발하고자 하였으며, 또한 기존 제품들과 차별화하기 위하여 휴대용으로 개발하여 차폐실이 아닌 일반 병실에서도 검사가 가능하도록 함에 따라 유소아의 청각 장애를 극복시키는데 기여하고자 하였다.
