标准摘要
[中文适用范围]： 本 SAE 标准规定了确定公路机动卡车、卡车牵引车和公共汽车最大外部声级的测试程序、环境和仪器。通过该测试程序获得的测试结果客观地测量了车辆在规定条件下发出的最大噪声水平。对使用中的车辆造成的烦恼的主观评价可能与这种类型的噪声水平测量没有直接关系。 [外文原描述]： This SAE Standard establishes the test procedure, environment, and instrumentation for determining the maximum exterior sound level for highway motor trucks, truck tractors, and buses. The test results obtained by this test procedure give an objective measure of the maximum noise level emitted by vehicles under a prescribed condition. A subjective rating of the annoyance caused by vehicles in use may not be directly related to this type of noise level measurement.Cross Reference: ANSI/S1.4,J184_201408
