The noise characteristics of the idle bandsaw were measured with sound intensity method. The values of sound intensity, vector chart, contour chart and mesh chart of noise were obtained.
使用声强法对木工带锯机的噪声特性进行了测量，测得三面的声强值和噪声的矢量图、高线图、三维图。
Sound intensity is vector, so it is meaningful to obtain 3-d sound intensity for identifying noise sources.
声强是矢量，因而获取三维声强对于噪声源识别具有重要意义。
