GB/T 23282-2009 in English

《GB/T 23282-2009锻压机械噪声声功率级测量方法》由TC220（全国锻压机械标准化技术委员会）归口，主管部门为中国机械工业联合会。
本标准规定了在包络锻压机械声源的测量表面上测量声压级以计算锻压机械噪声声功率级的方法。同时给出了声学环境、测量仪器及使用以及表面声压级及声功率级的计算方法。
本标准规定的方法只适用于在规定的动作规范时是稳态和非稳态的锻压机械噪声测量,而不适用于在规定的动作规范时是辐射脉冲噪声的锻压机械噪声测量。适用于具有一个反射面的符合规定要求的室内和室外环境。

Scope

This standard specifies the method for calculating the sound power level of forging machinery noise by measuring the sound pressure level on the measuring surface enveloping the sound source of forging machinery. At the same time, the acoustic environment, measuring instruments and their use, as well as the calculation methods of surface sound pressure level and sound power level are given. The method specified in this standard is only applicable to the noise measurement of forging machinery that is "steady state" and "unsteady state" in the specified action specification, but not for the forging machinery that radiates "pulse" noise in the specified action specification. noise measurement. Suitable for indoor and outdoor environments within regulatory requirements having a reflective surface.
