초록

B$\'{e}$k$\'{e}$sy 청력검사는 피검자의 청력 역치를 결정할 수있을 뿐만 아니라 누가현상을 추정 할 수 있고 난청의 병변위치를 규명하는데도 도움을 주는 청력검사 방법이다. 본 논문은 가격 경쟁력을 제공하기 위한 방법으로 PC 사운드카드를 사용하여 ANSI 표준을 준수하는 B$\'{e}$k$\'{e}$sy 청력검사 시스템의 개발에 대해 기술한다. 본 시스템은 동적으로 검사 신호를 생성하며, 실시간으로 검사 결과를 확인할 수 있는 인터페이스를 제공한다. 또한 표준에서 요구하는 최대 청력 레벨을 지원하기 위해 증폭기를 구현한다. 그리고 구현된 시스템이 ANSI 표준을 준수하는지 검증한다.

The B$\'{e}$k$\'{e}$syaudiometry makes possible to determine not only hearing threshold but also assumption of recruit phenomenon. Additionally, it is helpful to investigate cause of hearing loss. In this paper, we describe a development of PC based B$\'{e}$k$\'{e}$syaudiometer which complies with ANSI standards and provides cost competitiveness. It dynamically produces sound having required frequency and sound pressure level and supports audiogram interface showing test result at realtime. To provide ANSI defined maximum sound level, an amplifier has been developed. We have been verified our system whether it conforms to ANSI standards.
