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.
