ISO 1996-1:2016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的这一部分描述了对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 1996-1:2016未规定环境噪声限值。 注1:在声学中，描述声音的几种不同物理度量可以用分贝（e。 g、 声压、最大声压和等效连续声压）。对于相同的声音，与这些物理测量相对应的音量通常会有所不同。这通常会导致混乱。因此，有必要指定基本物理量（例如声压级、最大声压级和等效连续声压级）。 注2:在ISO 1996的本部分中，数量以分贝表示。然而，一些国家有效地以帕斯卡或帕斯卡平方秒表示基本物理量，如最大声压。 注3:ISO 1996-2涉及声压级的测定。

ISO 1996-1:2016 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. This part of ISO 1996 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 1996-1:2016 does not specify limits for environmental noise. NOTE 1 In acoustics, several different physical measures describing sound can have their level expressed in decibels (e.g. sound pressure, maximum sound pressure, and equivalent continuous sound pressure). The levels corresponding to these physical measures normally will differ for the same sound. This often leads to confusion. Therefore, it is necessary to specify the underlying physical quantity (e.g. sound pressure level, maximum sound pressure level, and equivalent continuous sound pressure level). NOTE 2 In this part of ISO 1996, quantities are expressed as levels in decibels. However, some countries validly express the underlying physical quantity, such as maximum sound pressure, in pascal or sound exposure in pascal-squared seconds. NOTE 3 ISO 1996？2 deals with the determination of sound pressure levels.
