| 摘 要： | 运动汽车噪声源的快速定位和精确测量是进行汽车噪声控制的重要基础,通过可视化的方法将噪声源及声场分布实时显示出来使这一过程更为高效直观.目前在运动汽车噪声测量领域有3种噪声可视化测量方法:远场声全息法.短时波束形成法和动态波叠加法.通过理论分析和仿真模拟对3种方法进行比较研究,并搭建了基于3种方法的仿真和实验系统,通过实验验证研究结果,得出研究结论.

| Abstract: | It is important to identify and locate the sound sources correctly and quickly in controlling vehicle noise.Visualization method makes it more efficient and intuitive in locating noise sources and displaying sound field in real time.Currently,there are three noise visualization methods widely used in measuring moving vehicle noise: the far-field acoustic holography method,short-time beamforming method and dynamic wave superposition method.In this paper,the theoretical analysis and simulation of the comparat... |
