[中文适用范围]： 本文件已被宣布为“稳定”，并且将不再接受货币定期审查。用户负责验证参考资料和持续适用性或技术要求。新技术可能存在。本 SAE 标准用于确定静态和就地动态机械（推土机、装载机、挖掘机和反铲）的外部 A 计权等效声功率级，类似于 ISO 6393 静态和 ISO 6395 动态声功率中获得的声功率测试程序。添加了 SAE J2130 涵盖的其他机器类型，特别是清扫机和洗地机，以及 SAE J111 涵盖的其他作业机械类型 [外文原描述]： This SAE Standard is used to determine the exterior A-weighted equivalent sound power level of static and in-place dynamic machines (dozer, loader, excavator, and backhoe) similar to the sound power obtained in ISO 6393 static and ISO 6395 dynamic sound power test procedures. Additional machine types, specifically sweepers and scrubbers, covered by SAE J2130 have been added, and other work machine types covered by SAE J1116 may be added with appropriate cycle descriptions and machine preparation. The recommended test procedures include conventional integrating sound pressure level methods or the sound intensity method using paired microphones. The sound intensity methodology provides a practical indoor alternative and permits measurement in the factory environment. The procedures in this document assume that the dominant sources are not highly sensitive to load (i.e., cooling fan, engine, track system). This test can be used as a substitute for the ISO 6393 static and ISO 6395 dynamic sound power tests for many machine types.The requirements for the machine setup and operation, and the microphone array and hemispherical measurement surface are given in this document. This document shall be used in conjunction with instrumentation manufacturer's recommendations and ISO 9614-1. The accompanying sound intensity procedure clarification is provided pending more widespread understanding of sound intensity.Cross Reference:
