| 中文摘要: |
| 为了进一步研究有限长线声源的声场特性,完善有限长线声源声场理论,建立了有限长线声源斜面声场的模型,提出了其理论计算方法。基于仿真结果和数据分析,探讨并得到了有限长线声源斜面声场特性的三个参数与斜面声场特性之间的关系。通过调整斜面倾角α、交点的位置r0以及有限长线声源的长度L,可以有效改善斜面声场的分布。 |
| 英文摘要: |
| To further research of the finite line sound source, the slope sound field module was built and a method on analysis of slope sound field was proposed which is significant to theoretical research and practical application on finite line sound source. Through simulation and data analysis, the influence to the slope sound field caused by three parameters which are related to the slope module is discussed. The relationship between three parameters and slope sound field was concluded. The slope sound field characteristics can be improved by choosing appropriate parameters. |
