| 摘 要： | 研究了钢板与橡胶共同组成的多层结构,在水、空气多重介质中斜入射时的声学特性,用传递矩阵法推导了多层结构的反射、透射系数的计算公式,并用数值方法进行求解.计算结果表明,增加消声橡胶层可以有效的降低多层结构的声反射能力,较好的达到降低目标声反射强度的目的.

| Abstract: | The multiple-layer structure,located between water and air,is composed of armor plates and rubber layers,in which the sound field is investigated.According to the transferring matrixes of single-layer and multiple-layer structure,the sound reflection and transmission coefficients are obtained by means of numeric computation. The calculated results show that the use of rubber could decrease the sound reflection intersity of multiple-layer srtucture,and reach the aim to eliminate noise effectively. |
