ISO 1996-1:2003定义了用于描述社区环境中噪声的基本量，并描述了基本评估程序。它还规定了评估环境噪声的方法，并就预测社区对各种环境噪声长期暴露的潜在烦恼反应提供了指导。声源可以是单独的，也可以是不同的组合。预测烦恼反应的方法仅限于人们居住的地区和相关的长期土地使用。社区对噪声的反应可能因观察到具有相同声级的声源而异。ISO 1996-1描述了具有不同特征的声音的调整。术语评级水平用于描述添加了一个或多个调整的物理声音预测或测量。根据这些评级水平，可以估计社区的长期反应。对声音进行单独或组合评估，在主管部门认为必要时，考虑其冲动性、音调和低频成分的特殊特征，以及道路交通噪声、其他形式的交通噪声（如飞机噪声）和工业噪声的不同特征。ISO 1996-1未规定环境噪声限值。

ISO 1996-1:2003 defines the basic quantities to be used for the description of noise in community environments and describes basic assessment procedures. It also specifies methods to assess environmental noise and gives guidance on predicting the potential annoyance response of a community to long-term exposure from various types of environmental noises. The sound sources can be separate or in various combinations. Application of the method to predict annoyance response is limited to areas where people reside and to related long-term land uses.Community response to noise can vary differently among sound sources that are observed to have the same acoustic levels. ISO 1996-1 describes adjustments for sounds that have different characteristics. The term rating level is used to describe physical sound predictions or measurements to which one or more adjustments have been added. On the basis of these rating levels, the long-term community response can be estimated.The sounds are assessed either singly or in combination, allowing for consideration, when deemed necessary by responsible authorities, of the special characteristics of their impulsiveness, tonality and low-frequency content, and for the different characteristics of road traffic noise, other forms of transportation noise (such as aircraft noise) and industrial noise.ISO 1996-1 does not specify limits for environmental noise.
