水筒中涂层模型降低噪声总声级的研究
The study of noise reduction by coating in a water tunnel
  
中文摘要:
      我们根据回转体模型的水筒噪声试验,分析了不同低表面能涂层模型在高、低频段降低噪声总声级的效果。一些涂层模型在高频噪声声级降低很多时引起了噪声总声级的降低.
英文摘要:
      Acoustic communication through the water medium is greatly hadicapped by the noise produced by the moving vehicle and its machinery.This paper presents a first attempt to predict the levels of the noise reduction by a coating composed of low surface energy as a function of the frequency performed with a rotating cylinder and measurement in the test of water tunnel. Some coatings can reduce the noise in highfrequency(≥2 .5kHz).
