본 연구에서는 비상시 인명피해의 위험요소인 연기발생에 따른 시야장애 상황을 연출하여 음성피난유도 시스템의 적용을 위한 모의실험을 실시하였으며 피험자들의 피난행동과 피난 대피시간을 조사 분석하였다. 피난유도음을 스피커 4개에서 동시에 발생시킬 경우, 대부분의 피험자는 방향감을 상실하고 지정된 지점으로 이동하는 시간도 비교적 길게 나타났다. 스피커 2개보다 1개에서 피난유도 멘트가 나왔을 때 방향감 및 피난행동에 가장 좋은 결과를 보여주었다. 또한 2개 이상의 스피커에서 피난유도 멘트가 동시에 발생되었을 때는 선행음효과를 활용하고, 스피커 설치가 가까울수록 피난유도 내용 및 방향감 인지가 높고 대피시간도 짧은 것으로 나타났다.
In this study, a simulated situation in which the visions of the evacuees were blocked by the smoke, which is one of the most dangerous factors that cause casualties in case of an emergency, was conducted for the evaluation of the performance of an evacuation guidance system. For this purpose, the behavior and time taken by the experiment subjects in simulated evacuation test were measured and analyzed. When the evacuation guidance sound signals were given by 4 speakers at the same time, most of the subject were disoriented and took generally longer in getting to the pre-designated evac point. And, using only one speaker instead of two showed a better result in terms of the evacuation behavior or and orientation. Also, when there were two or more speakers used for the broadcasting of the guidance message, it turned out that using Hass effect, and placing the speakers closer, could result in higher awareness of the guidance message and maintenance of the orientation, while it also made the subjects took short to get to the evac point.
Key Words: Hass Effect, evacuation, Evacuation guide systems, Evacuation performance
