本文件规定了在相关地点的靶场内，记录口径小于20毫米的射击或小于50克TNT当量的炸药爆炸产生的声压时程的方法，涉及射击者或靶场内任何其他人的声音暴露。声压的时程可以作为在感兴趣的位置进一步分析此类声音的基础。

This document specifies methods for recording the time history of the sound pressure produced either by shooting with calibres of less than 20？mm, or by detonation of explosive charges of less than 50？g TNT equivalent, within the shooting range at locations of interest, regarding the exposure to sound of the shooter, or any other person within the shooting range. The time history of the sound pressure can be the basis for further analyses of this type of sound at the locations of interest.
