소구경 화기의 사격음 특성에 대한 비교분석 연구

다국어 초록 (Multilingual Abstract)

In order to provide a basis data for design of small arms and their silencer, an experimental study on firing noise of small arms was performed around the muzzle of a gun. For this experimental comparison analysis, the target small arms were included most operating small arms in our country. The sound pressure levels were measured at a certain distance which was predetermined according to US army firing test procedure, TOP 3-2-045. By this experimental study, the sound pressure levels of 5.56 ㎜ caliber small arms are 143 ㏈ ~ 145.4 ㏈ and 7.62 ㎜ caliber small arms are 144 ㏈ ~ 145.2 ㏈. Between the heavy machine gun K12 and M60, the sound pressure level of K12 is slightly lower than M60.Also silencer for K14 snifer rifle was tested. Using this result, it has been found that the reduction effect of the silencer is 15.4 ㏈ but the improvements of silencer performance in the high frequency range have to be studied later on.
