摘要
选择受噪声影响的村屯段、城郊段为研究对象,通过分析三种声屏障材料的隔声量、造价、景观性、适用位置等因素,确定在村屯段设置轻质水泥声屏障,在城郊段设置中空铝塑复合板声屏障,根据《声屏障声学设计和测量规范》确定声屏障的设计降低值,经噪声实测达到了降噪的要求。
The sections of villages and suburbs that are influenced by noise are selected as the research objects. Through analyzing some factors like sound reduction index, cost of construction, landscape, applicable location and so on of three kinds of sound barrier materials, the setup of sound barrier with light weight cement in the section of villages andsound barrier with hollow aluminium - plastic composite panel in the section of surburbs is determined, and the designed noise reduction value of sound barrier is determined according to Norm on Acoustical Design and Measurement of Noise Barriers, and the requirement of noise reduction is met through actual measurement of noise.
