- Scope
- This standard specifies an engineering method (level 2 defined in GB/T 14529-1993); determination of the sound power level of a large multi-source factory, which is related to the evaluation of its environmental sound pressure level. These sound power levels can be used in predictive models for this type of evaluation. The method is limited to large plants with multiple noise sources (combinations of individual sources) whose main dimensions lie in the horizontal plane and where the noise radiation is substantially uniform in all horizontal directions. Unweighted sound pressure levels are measured in octave bands. The results obtained are expressed in octave-band sound power levels and, if desired, in A-weighted sound power levels.
