摘　　要：针对南京市典型道路的交通噪声控制措施,分别选取低噪声路面、声屏障、隔声窗3种噪声控制措施进行监测,监测显示低噪声路面对整体声级降噪有限,声屏障对于1kHz倍频带以上的中高频隔声相对较好,真空玻璃隔声窗能对低频噪声有显著改善。In allusion to the traffic noise control measurement for typical roads in Nanjing, low-noise road, noise barriers and windows for sound insulation are selected for monitoring. The results show that the low-noise roads are limited for overall noise reduction, and the noise barriers are relatively effective for 1kHz octave band frequency noise above, while the vacuum insulation windows can significantly improve low-frequency noise.
