摘要
应用声学原理建立声波在3种介质内传输的模型,通过理论推导得出透射系数表达式,可为分层复合隔声结构的透射系数和透射损失计算提供理论依据,为噪声控制工程中设计分层复合隔声结构提供参考。
The model of acoustic wave transmission in three kinds of media is established by applying acoustic principle,and the expression of transmission coefficient is obtained by theoretical derivation,which can provide theoretical basis for the calculation of transmission coefficient and transmission loss of layered composite sound insulation structure,and provide reference for the design of layered composite sound insulation structure in noise control engineering.
