摘要
通过引入激光定位的方法,提升了无指向性声源的指向性指数的校准准确度,同时设计了一套全自动无指向性声源校准方案,实现了在消声室中无指向性声源的快速校准。
In this study,the method of laser positioning was introduced to improve the calibration accuracy of the directivity index of omnidirectional sound sources,and a set of automatic omnidirectional sound source calibration scheme was designed to realize the rapid calibration of omnidirectional sound sources in the anechoic room.
