摘要
水声声管在低频水声测量中的应用十分广泛,不仅可以用来校准低频水声换能器,还可以用作水声材料及其构件的声学参数测量。随着矢量水听器研究工作的不断发展,在水声驻波声管中更加大了对质点振速的测量研究。在回顾了矢量水听器校准技术的发展历程和研究现状的基础上,对影响矢量水听器校准技术的因素进行了分析,同时给出了相应的研究成果,包括采用驻波管比较校准方法时,由于标准声压水听器和被测矢量水听器的置放方式引起的灵敏度校准结果高频失真,以及由于矢量水听器悬挂结构影响导致出现的灵敏度校准结果低频失真,并且对矢量水听器技术未来的发展方向进行了展望。
Application of underwater acoustic tube in low frequency underwater acoustic measurement is wide ranging,it can not only be used to calibrate low frequency underwater acoustic transducer,but also to measure acoustic parameters of underwater acoustic materials and their components.With the development of research on vector hydrophone,the measurement of particle velocity has been studied more and more in standing wave tube for underwater acoustic.Based on the review of the development history of vector hydrophone calibration technology and the current status of research,this paper analyzes the factors affecting the vector hydrophone calibration technology and presents the corresponding research results,at the same time,the corresponding research results are shown,including the high frequency distortion of sensitivity calibration results due to the positioning mode of reference acoustic pressure hydrophone and vector hydrophone under test,and the low frequency distortion of sensitivity calibration results due to the influence of vector hydrophone suspension structure when using comparative calibration method in the standing wave tube.In addition,the future development direction of vector hydrophone technology is prospected.
