摘要
在舰船球鼻艏内敷设吸声橡胶以降低噪音等不利因素对声纳基阵的影响,并对敷设与未敷设吸声材料进行分析研究,证实敷设吸声材料能显著降低噪音等级,为声纳提供安静的工作环境。
This paper studies the influence of laying noise-absorbing rubber in the bulbous bow to reduce noise and other adverse factors on the sonar array; and analyzes the results with or without noise-absorbing material to find that the noise-absorbing rubber can significantly lower the noise level, thus providing a quieter working environment for the sonar.
