该SAE标准相当于ISO 362-1:20 15，规定了在典型城市交通条件下测量M类和N类道路车辆发出噪声的工程方法。它不包括L1、L2、L3、L4和L5类车辆。 本规范旨在再现城市交通中正常驾驶期间主要噪声源产生的噪声水平。该方法旨在满足简单性的要求，只要它们与车辆操作条件下结果的再现性一致。 该测试方法需要仅在广阔的开放空间中获得的声学环境。此类条件通常在以下情况下提供: 用于监管认证和/或型式认证的车辆测量。 制造阶段的测量。 在官方测试站进行测量。

This SAE Standard is equivalent to ISO 362-1:2015 and specifies an engineering method for measuring the noise emitted by road vehicles of categories M and N under typical urban traffic conditions. It excludes vehicles of category L1, L2, L3, L4, and L5. The specifications are intended to reproduce the level of noise generated by the principal noise sources during normal driving in urban traffic. The method is designed to meet the requirements of simplicity as far as they are consistent with reproducibility of results under the operating conditions of the vehicle. The test method requires an acoustical environment that is obtained only in an extensive open space. Such conditions are usually provided for during: Measurements of vehicles for regulatory certification and/or type approval. Measurements at the manufacturing stage. Measurements at official testing stations.
