Friberg，Thompson等人，Wilson，Embleton和Russell，Kuttruff(仅适用于安装的房间)，Zetterling，Sergeyev等人开发了用于预测工业车间噪声水平的简化模型。(仅适用于未经处理的工作室)和霍奇森。他们预测八度频段或A加权稳态声压级作为源/接收器距离的函数。这些模型是通过将预测的声传播曲线与在30个有和没有吸声天花板处理的空置和安装的工业工作室中测得的声传播曲线进行比较来编程和评估的。在空荡荡的工作室里，谢尔盖耶夫等人、汤普森和霍奇森的模型工作得很好。泽特林模型的表现还算不错。其他模型是不准确的。在大多数情况下，模型低估了水平。随着吸收处理的增加，Friberg、Wilson、Zetterling和Embleton和Russell模型的精度有所提高，Thompson和Hodgson模型的精度有所提高。
Simplified models for predicting noise levels in industrial workrooms have been developed by Friberg, Thompson et al., Wilson, Embleton and Russell, Kuttruff (“diffuse” and “specular” models applicable to fitted rooms only), Zetterling, Sergeyev et al. (applicable only to untreated workrooms), and Hodgson. They predict octave-band or A-weighted steady-state sound-pressure level as a function of source/receiver distance. These models have been programmed and evaluated by comparing predicted sound-propagation curves with those measured in 30 empty and fitted industrial workrooms with and without absorptive ceiling treatments. In empty workrooms the Sergeyev et al., Thompson, and Hodgson models worked quite well. The Zetterling model performed moderately well. The other models were inaccurate. Models underestimated levels in most cases. With the addition of absorbent treatments the accuracy of the Friberg, Wilson, Zetterling, and Embleton and Russell models improved; that of the Thompson and Hodgson models w...
