本标准是声压法测定噪声源声功率级的系列标准之一。本标准规定了在消声室和半消声室中测量包围噪声源的测量表面上的声压级,从而确定噪声源的声功率级或声能量级的测量方法。它给出了对测试环境和仪器的要求,同时给出了由测得的表面声压级计算其声功率级或声能量级的方法,保证所得到的结果具有1级准确度。本标准规定的方法适用于所有类型噪声源的测量。噪声源可以是设备、机器、组件或附件。可测量声源的最大尺寸取决于测量包络面假想球(或半球)的半径。本标准与GB/T6882—1986比较,增加了以下内容:
———对鉴定声源指向性进行了严格限制;
———声能量级的测定;
———对特定噪声使用的消声室和半消声室的鉴定方法;
———半消声室精密法增加了测点;
———半自由场中传声器的子午线路径;
———半自由场中传声器的螺旋线路径;
———由1/3倍频带声功率级计算A 计权声功率级;
———对测量不确定度的分析。
