标准范围

ISO 13472的这一部分描述了现场测量道路吸声系数的试验方法表面作为频率的函数，范围从到。假设为正常发病率。然而，该测试方法可以应用于斜入射，尽管有一些限制限制（见附件F）。本试验方法适用于以下应用:-根据ISO 10844测定测试轨道的吸声性能，并有限制，以及其他类似标准；-实际使用中路面吸声性能的测定；-路面吸声设计规范与车辆实际性能数据的比较施工工程完工后的表面。用这种方法也可以确定复反射系数。

This part of ISO 13472 describes a test method for measuring in situ the sound absorption coefficient of roadsurfaces as a function of frequency in the range from to.Normal incidence is assumed. However, the test method can be applied at oblique incidence although with somelimitations (see annex F). The test method is intended for the following applications:— determination of the sound absorption properties of test tracks according to ISO 10844, with limitations, andother similar standards;— determination of the sound absorption properties of road surfaces in actual use;— comparison of sound absorption design specifications of road surfaces with actual performance data of thesurface after completion of the construction work.The complex reflection factor can also be determined by this method.
