河南省新乡县小冀镇环境噪声的测量与分析

Measurement and Analysis of Environmental Noise in Xiaoji Town, Xinxiang County, Henan Province

为了了解河南省新乡县小冀镇的环境噪声现状,在小冀镇进行了环境噪声监测,根据监测结果绘制了小冀镇白天环境噪声等值线图,分析了该镇白天环境噪声分布情况和主要的噪声源及噪声污染程度。研究结果显示,小冀镇白天的环境噪声分布于50~95 dB (A)之间,噪声来源以交通噪声和生活噪声为主,大部分区域环境噪声质量处于坏–恶化的级别,只有少数区域噪声环境一般,提出了减少和降低噪声污染的措施,为环境主管部门决策提供科学依据。

In order to understand the present situation of environmental noise in Xiaoji town, Xinxiang county, Henan province, environmental noise monitoring was carried out. According to the results of practical monitoring, environmental noise isoline maps of Xiaoji town during the day were drawn, and the distribution of environmental noise, main noise sources and the degree of noise pollution in the town were analyzed. The results show that the value of environmental noise is distributed between 50 dB (A) and 95 dB (A) in daytime. Noise sources are mainly traffic noise and living noise. The quality of environmental noise in most areas is at the level of bad-deterioration, and only a few areas have general noise environment. Measures to cut down noise pollution are put forward, which provided scientific basis for the decision of the environmental authorities.
