标准摘要
[中文适用范围]： 本 SAE 推荐做法规定了用于确定雪地摩托车在固定测试模式下的声级的测试程序、环境和仪器。该测试方法旨在提供排气和其他发动机噪声的准确测量，并可用于评估新的和在用的雪地摩托车，以确定是否符合噪声控制法规。使用此测试方法获得的声级测量值并不旨在作为整体机器噪声的工程确定。为此，建议使用 SAE J 192。 [外文原描述]： This SAE Standard establishes the test procedure, environment, and instrumentation for determining the sound levels of snowmobiles in the stationary test mode. This test method is intended to provide an accurate measurement of exhaust and other engine noise and may be used to evaluate new and in-use snowmobiles to determine compliance with noise control regulations. Sound level measurements obtained with this test method are not intended as an engineering determination of overall machine noise. For this purpose, the use of SAE J192 is recommended.Cross Reference: ANSIS1.4,J192_201901,J33_201707,J47_202006
