摘要
道路声屏障降噪理论的发展是新型高效声屏障设计的基础,根据声屏障降噪理论的发展历程将其分为几何与波动声学理论、试验与半经验理论以及边界元理论三种,综述了各自的基本原理和研究进展,比较分析了三种理论的特点和实用范围,为声屏障优化设计提供理论参考。
Development of insertion loss theory of road noise barrier is the base of designing a new style and high-efficiency barrier. In this paper, insertion loss theory was divided into three: geometry and wave acoustical theory, test and half-experiences theory and boundary element method according to theirs development course. Basic principle and advance of each theory was presented and character and applied field was analyzed. It provided the theory references for barrier optimum design.
