| 摘 要： | 文章对声强测量中的声场指数和有关判据进行了阐述，以Ｃ６１６Ａ－１型精密车床为对象，选择三种不同的测量条件进行了声功率级的测定．结果分析表明：采用双传声器互谱声强法测量噪声源声功率时，只要按照ＩＳＯ９６１４－１中规定的判据进一行测量，就可以达到预期精度的结果，同时还可以优化测量条件．

| Abstract: | The sound field indicators and relevant criteria in sound intensity measurement (ISO 9614 - 1 ) are discussed in this P8per. Three different kinds of measuring conditions have been made on a tool machine (type C616A- 1 ) to determine its sound power level. The results and analysis show that the sound power level can reach to the expected accuracy according to the criteria proposed in ISO 9614- 1, and the measuring conditions can be optimized. |
