摘　　要：对于一定厚度的水中气幕和声边界条件,通过气幕声反射和声透射理论模型的推导,构建了考虑多体多次散射情况的气幕声插入损失计算模型,并采用与气幕实测谱在频域相比较的方法,实现了用气幕实验数据逆算气幕实际结构参数和数值求解气幕实际声插入损失.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.
