Abstract
ABLB(양측 귀 교대 평형) 검사는 누가현상에 기초한 감각신경성 난청의 세부 병변을 감별하기 위한 검사중 하나이다. 본 논문은 자동 ABLB 검사 소프트웨어를 기술한다. 이 소프트웨어는 ABLB 검사 주파수 및 검사 시작음을 자동으로 결정한다. 또한 검사 음에 대한 피검자의 반응을 분석하여 다음 검사를 결정하는 알고리즘을 지원한다. 또, 피검자의 ABLB 검사 제어 및 모니터링을 위한 인터페이스를 제공하고 검사 결과를 Ladder Diagram으로 나타낸다. 디지털 오실로스코프를 이용하여 ABLB 검사 음이 정확하게 출력되는지 확인하였다. ABLB(Alternate Binaural Loudness Balance) test is one of the medical assessments to diagnose detailed lesion of sensory-neural hearing loss based on a recruitment phenomenon. This paper describes an Auto ABLB test software. This software automatically decides test frequency and intensity of first test tone. And it supports an automatic algorithm that analyses the subject's reponses in the current step and then decides intensity of tone provided in next step. Also, this software supports an interface to control and monitor subject's ABLB test. The assessment result is represented by a ladder diagram. The output of this software has been verified using a digital oscilloscope.
