介绍了在制造商工厂进行测试时，齿轮减速器或增速器产生的声压级验收测试和报告的推荐方法。（由于环境、安装和系统影响的差异，制造商的测试结果不应直接转化为系统安装。）包括关于声功率级的附录。ANSI/AGMA 6025-C90的修订版。

Describes a recommended method of acceptance testing and reporting of the sound pressure levels generated by a gear speed reducer or increaser when tested at the manufacturer's facility. (Manufacturer's test results should not be expected to translate directly to the system installation because of differences in environment, mounting, and system effects.) Includes an appendix on sound power levels. Revision of ANSI/AGMA 6025-C90.
