요약
공동주택 화재 발생시 인명피해 최소화 및 재실자의 신속한 대피를 위해서는 화재 발생 사실이 경보음을 통해 전체 세대로 전달되어야 한다. 공동주택의 경우 엘리베이터 실과 같은 공용공간에 경종이 설치되어 있으나, 세대내 공간으로 경보음이 충분히 전달되지 못하는 것으로 알려져 있다. 본 연구에서는 실제 공동주택에서의 주,야간 소음을 측정하여 공동주택 세대 내 소음 발생 실태를 조사하고 세대내 공간으로의 경보음 전달 정도를 분석하였다. 엘리베이터 실에서 발생되는 경보음이 공동주택 내부로 전달되는 경우 방화문 및 방문의 차음성능으로 인해 충분히 전달되지 못하는 것으로 나타났다. 공동주택 내에서 발생되는 각종 소음 레벨을 고려하면 공동주택 외부에서 발생되는 경보음을 청취하여 피난행동을 시작하는 데는 어려움이 있는 것으로 판단된다. 이를 개선하기 위해 공동주택 거실의 월패드와 각 방별로 경보음 발생기를 설치한 경우에 대하여 음향시뮬레이션을 실시하였다. 각 방별로 경보음 발생기를 설치한 경우에서만 배경소음 + 15 dB 기준과 75 dB (A) 기준을 만족하는 것으로 나타났다.
Abstract
To reduce the number of casualties in the case of fire, an alarm sound needs to be delivered to the people who remain in the apartment unit. On the other hand, it was reported that the fire alarm sound generated in the elevator hall was not delivered sufficiently to the people staying in the apartment units. In this study, the background noise level and noise level generated in an apartment unit were measured during the day and night time. In addition, the transmission of the fire alarm sound into the each room of apartment units was simulated and compared with the background noise level. The fire alarm sound generated in the elevator halls was reduced by the fire door and doors, and was not transmitted sufficiently into the internal spaces of the apartment units. Starting evacuation action was difficult after hearing the fire alarm sound generated outside the apartment units. To improve the transmission of an alarm sound to the inner spaces of apartment units, an acoustic simulation was carried out for cases where the alarm sound generator was installed on a wall-pad in the living room and the alarm sound generator was installed on the ceiling of each rooms in apartment units. Background noise of + 15 dB and 75 dB (A) were satisfied when alarm sound generator was installed on the ceiling of each room.
