People in the advanced society have deep interest in such environmental problems as noise, air quality, water pollution, etc. This paper submits the result of the research on the noise In the surroundings of the butane can explosion location. First, the noise level measured in a residential area, 245 meters' away from the butane can explosion location, was 59.3 dB. Also, the noise level measured in the IGUP (International Graduate University of Peace), 300 meters' away from the explosion site, was 52.5 dB. Second, the above noise levels are lower than the level specified In the Environmental Standard (65 dB), which represented that the experiment was safe. Third, the noise level in a place away from the butane can explosion location varied in accordance with the direction of the wind. Consequently, the noise in all locations (the places where damage to people is expected) surrounding the experimental butane can explosion location was measured to identify the effect of the wind irection.
