ISO 8579的本部分规定了确定齿轮机构和齿轮马达气载声发射所需的说明和标准化条件。它还规定了允许的测量方法，以及用于测试的操作和安装条件。 ISO 8579的本部分旨在通过使用，确保在所用基本测量方法的准确度等级确定的规定限值内，测定气载声发射特性的再现性。ISO 8579本部分允许的声音测量方法为工程方法（2级）和测量方法（3级）。

This part of ISO 8579 specifies the instructions and standardized conditions necessary for the determination of the airborne sound emission of gear units and gearmotors. It also specifies the allowed measurement methods, together with the operating and mounting conditions used for the test. This part of ISO 8579 has the aim of ensuring, with its use, the reproducibility of the determination of the airborne sound emission characteristics within specified limits determined by the grade of accuracy of the basic measurement method used. The sound measurement methods allowed by this part of ISO 8579 are engineering methods (grade 2) and survey methods (grade 3).
