Abstract

SAE RP J1096 and CSA Standard Z107.22 are compared in terms of their performance as predictors of pass-by sound levels measured in accordance with SAE RP J366b. The comparinon is based on the results of tests on 60 diesel trucks covering a range of ages, sound levels and configurations. The CSA procedure is found to be at least as good a predictor of pass-by sound levels as RP J1096 and can be used on smaller and noisier sites. The results of some exploratory measurements of the effects of wind and temperature gradients on the repeatability of the two procedures are also presented and discussed.

卡车外部声级两种固定测量方法的比较

比较了SAE RP J1096和CSA标准Z107.22作为根据SAE RP J366b测量的行车声级预测指标的性能。这一比较是根据对60辆柴油卡车的测试结果得出的，这些卡车涵盖了不同的车龄、声级和配置。发现CSA程序至少与RP J1096一样可以很好地预测经过的声级，并且可以在较小和嘈杂的站点上使用。本文还介绍和讨论了风和温度梯度对这两种方法的重复性影响的一些探索性测量结果。
