赣州市城区交通噪声污染水平调查

目的]通过对赣州市城区交通主干道的昼夜交通噪声实地监测,了解赣州市城区交通主干道噪声污染的分布状况。方法]采用TES-1357声级仪,测量文明大道、红旗大道、八一四大道、文清路、厚德路、大公路的噪声值,与环境噪声标准比较并进行卫生评价。资料采用统计软件SPSS14.0进行处理。结果]赣州市监测路段的平均交通噪声值在73.3～74.9 dB之间,超出《城市区域环境噪声标准(1993)》3～5 dB,噪声污染比较严重。通过分析赣州市城区主干道交通噪声在时间和空间上的差异,发现赣州市交通噪声的时间分布特点为早上8:00、中午12:00和晚上18:00这3个时间段噪声值较高,同时发现大公路污染最严重。结论调查证实赣州市交通噪声污染比较严重,应引起有关部门重视。

INVESTIGATION AND ANALYSIS OF TRAFFIC NOISE LEVELS IN GANZHOU CITY

Objective]To find the distribution of noise pollution of trunk road in Ganzhou City through monitoring the traffic noise of the main roads in Ganzhou City day and night.Methods]The noise values of Wenming Boulevard,Hongqi Boulevard,Bayisi Boulevard,Wenqing Road,Houde Road and Dagong Road were measured by TES-1357 sound level meter,then compared the noise values with environmental noise standards and conducted health assessment.All the data were analyzed by the statistic software SPSS14.0.Results]The average value of traffic noise of monitoring section of the road in Ganzhou city was 73.3-74.9dB which was beyond the"Urban Area Environmental Noise Standards(1993)"to 3-5dB.The noise pollution was relatively serious.We analyzed the differences in time and space distribution of the traffic noise in the main roads in Ganzhou city.It was found that the traffic noise levels in 8:00,12:00 and 18:00 were highest and the most polluted road was Dagong Road.Conclusion]The investigation confirms that traffic noise pollution in Ganzhou City is serious.The relevant departments must pay attention to it.
