摘　　要：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、等高线图、三维图。由这些数据和线图可以全面了解带锯机的噪声分布情况．以便分析和控制噪声。The noise characteristics of the idle bandsaw were measured with sound intensity method. Thevalues of sound intensity. vector chart, contour chart and mesh chart of noise were obtained. Distributedstate of noise could be comprehended according to these data and charts, thereby the noise of bandsawcould be controlled.
