摘要
为了解延安大学男生公寓的声环境质量,通过现场监测和问卷调查,对公寓及周边道路进行声环境评价。结果表明:男生公寓的噪声级与室内夜间允许标准值差异极显著(t=3.31,P<0.01),超出标准;监测宿舍的PNC值为55,高出推荐值,舒适度较差;主要噪声源交通噪声与车流量成正相关(r=0.756,P<0.01)。结合现场环境特征,提出绿化工程治理、强化交通管理和宣传教育联合防范治理的措施。
The quality of acoustic environment of Yan'an University students apartment was analyzed. Noise measurement and surveying on noise environment of the apartment building of Yan'an University were carried out through on-site monitoring and survey. The results showed that there was extremely significant( t = 3. 31,P 0. 01) between the indoor ambient noise of the apartment building and the indoor ambient noise standard,causing beyond these standard requirements. The PNC of the monitoring dormitory was 55,which exceeded the recommended value,meaning that there was not very comfortable. Meanwhile,there was positive correlation( r = 0. 756,P 0. 01) between the traffic noise and the traffic volume. In addition,some proposals for environmental noise reduction had been presented such as greening project governance,strengthen traffic management and education.
