标准摘要
[中文适用范围]： 本文件规定了一种相对简单的工程方法，用于确定小型可移动噪声源的声功率级。 本文件中规定的方法适用于测量指定频率范围内的所有类型的噪声，但 ISO 3744 和 ISO 3745 涵盖的由孤立的声能突发组成的脉冲噪声除外。 注：不同类型噪声的分类是ISO 12001 中给出。 [外文原描述]： ISO 3743-2:2018 specifies a relatively simple engineering method for determining the sound power levels of small, movable noise sources. The methods specified in this document are suitable for measurements of all types of noise within a specified frequency range, except impulsive noise consisting of isolated bursts of sound energy which are covered by ISO 3744 and ISO 3745. NOTE A classification of different types of noise is given in ISO 12001.
