摘　　要：对泡沫铝和吸音棉内填在声屏障吸声板的检测结果进行了分析、比较。作者结合沈阳市的交通道路情况,提出了噪声综合治理措施。工程实践证明:采用内填吸音棉的吸声板,可有效降低噪声5-12d B。Testing result of the foamed aluminum and the absorbent cotton use in the acoustic panel of the noise barrier was analyzed and compared. Based on the traffic condition of Shenyang city, the authors propose the comprehensive measures. Meanwhile, combined with a practical case,if absorbent cotton is used in the acoustic panel,the noise can be decreased 5-12 d B.
