The noise transmission of aeronautical panels is an important phase of the design process of an airplane. In this work an analytical Navier-type solution, based on higher-order layer-wise shell models, is proposed for the analysis of the sound insulation of laminated panels. The considered multilayered structures are laminated with cross-ply composite layers embedded with interlaminar viscoelastic sheets. The use of the soft interlayers permits to have a passive insulation effect in the study of the sound transmission. In order to take into account the frequency depedent properties of a realistic viscoelastic layer, the damping behavior is modeled through a fractional derivative Zener model. The Rayleigh integral method is used to extrapolate the acoustic indicators for the sound transmission analysis. Some results are presented to validate the efficiency of the present approach, comparing the present solutions with others taken from the literature.

航空板的噪声传播是飞机设计过程的重要阶段。在这项工作中，提出了一种基于高阶逐层壳模型的解析Navier型解决方案，用于分析层压板的隔音效果。所考虑的多层结构层压有嵌入层间粘弹性片材的交叉复合材料层。在研究声音传输时，使用软质中间层可以具有被动的隔声效果。为了考虑实际粘弹性层的频率依赖特性，通过分数导数齐纳模型对阻尼行为进行建模。瑞利积分法用于推断声学指标，以进行声音传输分析。
