Scope

GB/T 20246-2006 is the English-translated version of 声学用于评价环境声压级的多声源工厂的声功率级测定工程法.

GB/T 20246-2006 — This standard specifies an engineering method: Determination of large multi- source sound power level of the factory, which relates to the evaluation of its environmental SPL.

These sound power levels can be used for such an evaluation forecasting model. This method is limited to a plurality of noise sources (the combination of the individual sound sources) of large plants, the main dimension in a horizontal plane, the horizontal direction noise at all radiation is basically the same.
