标准摘要
[中文适用范围]： 本文件规定了一种计算方法（符合ISO 17201-4标准），用于根据非声学数据估算口径小于20毫米的枪支和当量小于50克TNT的爆炸所产生的枪口爆轰声和爆炸的声源数据。本文件适用于那些没有声源测量数据的情况。本文件也可用作枪口爆轰声测量数据之间的插值方法。声源数据以覆盖频率范围从12.5 Hz到10 kHz的谱角声源能量形式给出，可用于声传播计算的输入数据。本文件不适用于预测用于评估听力损伤的声级；也不可用于预测在非线性声学适用距离范围内的声压级或声暴露级。 [外文原描述]： This document specifies a computational method (in line with ISO 17201-4) for estimating the acoustic source data of muzzle blast and explosions on the basis of non-acoustic data for firearms with calibres less than 20 mm and explosions less than 50 g TNT equivalent. This document addresses those cases where no source measurements exist. This document can also be used as an interpolation method between measurements of muzzle blast. Source data are given in terms of spectral angular source energy covering the frequency range from 12,5 Hz to 10 kHz and can be used as data input for sound propagation calculation. This document does not apply to the prediction of sound levels for the assessment of hearing damage; nor can it be used to predict sound pressure levels or sound exposure levels at distances where linear acoustics do not apply.
