A study on the effect of wind around on sound fire extinguisher

초록

Modern buildings are becoming more taller, and the interior is becoming more complicated. A new strategy for conflagration has become necessary due to changes in the fire fighting environment. Sound Fire Extinguisher is designed to be used in various fire fighting environments by escaping existing extinguishable method. A Sound Fire Extinguisher needs to consider wind around as it takes advantage of the sound characteristics. In this paper, we investigated the effect of wind around on the Sound Fire Extinguisher through experiments. Experimental results show that even if the wind is supplied vertically on the sound propagation pathways, the effect on the arrival position of the transmitted sound or the sound level reached is insignificant. However, when the wind was supplied, the sound level became somewhat irregular. From these results, we can confirm that the sound component of the Sound Fire Extinguisher must be supplied considering the irregularity of the sound level caused by the wind around. © International Research Publication House.
