| 中文摘要: |
| 基于空间移动的标准点声源设计，建立声源定位系统动态校准装置。提出空气声声源定位系统动态校准方法，获得声源定位系统动态定位实验测量结果，分析影响动态定位结果的主要因素，并进行测量结果不确定度的评定。为车辆通过噪声源定位、飞机器飞行中噪声源定位的实验室动态校准提供了计量技术支撑。 |
| 英文摘要: |
| Based on design of point sound source which can be moved in space, calibration device used in calibration of sound source localization system was built. Dynamic characteristics evaluated methods were put forward, experiment results were acquired and main influences were analyzed. Uncertainties of calibration results were evaluated. It is useful to support the calibration technique for lab calibration of dynamic characteristics of sound source localization system using in automobile and aero vehicle movement noise identification. |
