摘要

研制的矢量水听器自动校准系统在水声计量领域具有重要的应用价值,能够实现低频范围内矢量水听器的自动校准。利用动态信号采集卡采集被测信号和标准水听器的输出信号,对驻波管内的声场分布进行了测量分析,对系统的测量不确定度进行了分析评定,对声压灵敏度进行了比对测试。该系统校准矢量水听器的扩展不确定度为1.6dB。

Abstract

Auto-calibration system of vector hydrophone has very important value in acoustic measurement. The system can accomplish low frequency auto-calibration of vector hydrophone. It can measure the signal amplitude of the standard hydrophone by dynamic signal acquisition. The sound field distribution is tested in the standing wave field. The standard uncertainty and expanded uncertainty of the system are analyzed and discussed. The comparison testing is given for pressure sensitivity. The expanded uncertainty of the system is 1.6dB.
