    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.
