【摘要】 水听器的灵敏度一般都在水中测量,本文介绍了一种在空气中测量小尺寸水听器灵敏度的方法。利用不同腔体的组合设计来实现对空气中声波传播路径的控制,最终解决了在空气中测试水听器灵敏度所需的声场问题。利用标准水听器比较法实现了水听器灵敏度空气中的测量,并与水中结果比对,获得了满意的效果。更多还原

【Abstract】 The sensitivity of hydrophones is generally measured in water.This paper describes a method for measuring the sensitivity of small hydrophones in air.The combined design of different cavities is used to control the acoustic wave propagation path in the air,and finally solves the sound field problem required to test the sensitivity of the hydrophone in the air.The standard hydrophone comparison method is used to measure the sensitivity of the hydrophone in the air,and it is compared with the results in the water,and satisfactory results are obtained.更多还原
