标准摘要
[中文适用范围]： 本文件描述了如何确定声压级，作为评估环境噪声限制或空间研究中情景比较的基础。 测定可以通过直接测量和通过计算外推测量结果来进行。 本文件主要供室外使用，但也为室内测量提供了一些指导。 它很灵活，并且在很大程度上，用户可以确定测量工作量以及相应的测量不确定度，测量不确定度在每种情况下确定并报告。 因此，没有设置允许最大不确定性的限制。 通常，测量结果与计算相结合，以校正与实际测量期间不同的参考操作或传播条件。 本文件适用于各种环境噪声源，如道路和轨道交通噪声、飞机噪声和工业噪声。 [外文原描述]： ISO 1996-2:2017 describes how sound pressure levels intended as a basis for assessing environmental noise limits or comparison of scenarios in spatial studies can be determined. Determination can be done by direct measurement and by extrapolation of measurement results by means of calculation. This document is primarily intended to be used outdoors but some guidance is given for indoor measurements as well. It is flexible and to a large extent, the user determines the measurement effort and, accordingly, the measurement uncertainty, which is determined and reported in each case. Thus, no limits for allowable maximum uncertainty are set up. Often, the measurement results are combined with calculations to correct for reference operating or propagation conditions different from those during the actual measurement. This document can be applied on all kinds of environmental noise sources, such as road and rail traffic noise, aircraft noise and industrial noise.
