水面舰船声学特性的类比及其评价

传统的水面舰船声学设计评价方法在应用上存在着局限性，为进一步发展和完善，通过对总声级声学特性类比、声频范围和超声频段声学特性、实船检测声学特点和实船声隐身战术技术要求制订等进行广泛论述与类比探讨的基础上，指出了现有方法在总声级确定、声学特性预报和实船检测等方面的不足，提出了较为合理的水面舰船声学特性的类比及其评价方法，即以特定频段的线谱分析来评定其声学性能。

Analogy and Evaluation of Acoustic Characteristics for Surface Ships

The traditional method for evaluating acoustic design of surface ship should be further improved for its application limits. In this paper, the disadvantages over determination of overall acoustic noise level, prediction of acoustic characteristic and real ship test etc. , using this method, are pointed out. These are done through an in-depth analysis and discussion in the aspects of analogy of characteristics of overall acoustic noise level, the characteristics for different audio and ultrasonic range, real ship test as well as development of technical and tactical requirements for stealth design. Based on these studies, a more sound method for analogy and evaluation of acoustic characteristic, which is carried out by a line spectrum analysis within a special frequency range, is put forward.
