摘要： 采用响应曲面法和Box-Behnken设计优化声屏障设计参数。以声屏障设计高度、长度、起点桩号为考察自变量，以声屏障对敏感区域内三处受声点理论插入损失、工程造价为考察因变量，构建多元二次回归模型考察因变量与自变量间的函数关系。设定以敏感区域内声环境质量达标、工程造价最低为优化目标，利用Minitab软件优化分析得到声屏障最优设计参数。

Abstract: the Box-Behnken design and response surface method were applied to optimize the parameters of noise barriers. The height, length and initial stake of noise barrier were studied as arguments, while the insertion loss of three sound-sensitive points, construction cost as variables. Quadratic equation models were developed to express the functional relationship between arguments and variables. Optimization parameters of noise barrier were obtained by Minitab analysis, basing on the goals of acoustic environmental standard in sensitive area, as well as minimization of construction cost.

Key words: coustics, noise barriers, insertion loss, response surface methodology, optimization
