요약
공동주택의 복잡한 평면 구조와 향상된 벽간 차음성능으로 인해 화재상황의 전달 및 인지가 어려워 피해가 증가되고 있는 실정이다. 본 연구에서는 국내 공동주택 평면 형태를 대상으로 소방시설 중 비상방송설비의 명료성에 대한 실태분석을 진행하였다. 아울러 피난방송의 명확한 인지를 위한 음성명료도 개선 방안을 시뮬레이션을 통해 분석하였다. 현장측정 결과 72, 84, 101 Type 모두 국내 경보설비기준인 90 dBA를 R1 지점에서 만족하지 못하는 것으로 나타났다. 또한 72 Type의 L1 지점(거실) 79.8 dBA를 제외하고는 모든 측정지점에서 출입문을 열었을 때와 닫았을 때 모두 NFPA 기준 75 dBA를 만족하지 못하는 것으로 평가되었다. 침실의 출입문 개구 상태를 기준으로 국내 화재안전기준에서 제시된 1 m 이격지점에서 90 dBA 이상을 만족시 각 침실에서 NFPA 기준인 음압레벨 75 dBA와 CIS 0.7을 만족하였다.
Abstract
Due to the complicated plan structure of the apartment units and the improved room-to-room sound insulation performance, it is difficult to communicate and recognize the fire situation by emergency broadcast equipment. In this study, speech intelligibility was measured and analyzed for three types of apartment unit by emergency broadcast equipment on various measurement points. Simulations were also conducted to improve the speech intelligibility. As a result of field measurements 72, 84, and 101 Type were not satisfied with NFSC standard of 90 dBA at the point of 1 m distance from source. In addition, it was evaluated that 75 dBA and CIS 0.7 of NFPA standard was not satisfied at all measurement points except for the 72 Type at living room point with door opened condition. Based on the door opened condition of the bedroom, it satisfied the NFPA of 75 dBA and CIS 0.7 in each bedroom when more than 90 dBA was satisfied at the 1 m separation point provided in NFSC standard.
