标准范围

本文件规定了在给定接收点预测单次放炮的放炮声暴露水平的方法。给出了根据声暴露水平计算其他声学指数的指南。该预测基于ISO 17201-1中定义的炮口冲击波的角源能量分布，或使用ISO 17201-2中的值进行计算。本文件适用于口径小于20毫米的武器或小于50克TNT当量的炸药，在峰值压力（包括弹丸声的贡献）小于1 kPa（154 dB）的距离处。注:可适用国家或其他更严格的法规。

This document specifies methods of predicting the sound exposure level of shooting sound for a single shot at a given reception point. Guidelines are given to calculate other acoustic indices from the sound exposure level. The prediction is based on the angular source energy distribution of the muzzle blast as defined in ISO 17201-1 or calculated using values from ISO 17201-2.This document applies to weapons with calibres of less than 20 mm or explosive charges of less than 50 g TNT equivalent, at distances where peak pressures, including the contribution from projectile sound, are less than 1 kPa (154 dB).NOTE National or other regulations, which could be more stringent, can apply.
