| Abstract: | For the underwater bubble screen with certain thickness and the acoustic boundary conditions, the theoretical model for sound reflection and transmission through the bubble screen is derived in this paper, by which the bubble screen sound insertion loss calculation model in the case of multi-body multi-dispersion is presented. The method of comparison with measured data in frequency domain is adopted to realize the inverse calculation of actual structure parameters by utilizing acoustic experimental data. Therefore, the insertion loss of the bubble screen can be calculated. |
