Summarization of acoustic parameters of underwater materials and the acoustic tube measurement method

简要阐述了水声材料产品研制过程中水声材料及其声学参数测量的重要意义和存在的问题,详细论述了水声材料声学参数分类及相应的测量方式,归纳了脉冲法、驻波法和行波法声管各自的测量原理和适用的条件,以及声管测量技术的发展趋势,最后总结了通过声管测量水声材料声学参数时,对测量声管和被测量样品的一般要求。

The significance of underwater materials and measurement of acoustic parameters in the design process of underwater acoustic products are briefly explained. The existing problems of acoustic tube measurement are also men- tioned. The types underwater acoustic parameters and the corresponding measurement ways for them are discussed in detail. Then the theory and application contition of acoustic tube measurement methods, including impulse wave, standing wave and traveling wave method, are analyzed respectively. The trends of the acoustic tube measurement me- thod are summarized also. The general requirements for acoustical tube and measuring samples, which must be satisfied in the measurement, are described in this paper.
