环境噪声是在工业生产、建筑施工、交通运输和社会生活中所产生的干扰周围环境的声音。环境噪声按区域可分为城市环境噪声、农村环境噪声和海洋环境噪声等。城市环境噪声又可分为工业噪声、建筑施工噪声、交通运输噪声和社会生活噪声等。 相似文献

噪声地图是由道路交通噪声、铁路噪声、工业噪声和机场噪声等对城市地图上每个接收点的叠加噪声值拟合图像绘制而成。它为城市规划、城市环境噪声管理提供了依据,也是检验噪声污染防治技术措施和规划控制措施有效性的重要手段。随着信息化程度的日益提高,应该加强GIS等具有空间分析功能的技术系统与噪声预测模型的结合,建立符合我国实际情况的通用模型,使噪声地图发挥更准确的决策作用。 相似文献

Levels and Influencing Factors of Noise Pollution from Small-Scale Industries (SSIs) in a Developing Country 总被引:1,自引:0,他引:1
Mbuligwe SE 《Environmental management》2004,33(6):830-839
A study was carried out to determine levels and factors that influence noise pollution from small-scale industries (SSIs) in Dar es Salaam City Tanzania. Two sites for wood- and metalworks industries were investigated. Both sites exhibited equivalent noise levels higher than 90.0 dBA, the permissible exposure level limit for occupational noise. At a woodworks SSI, noise levels were found to correlate well with machine-use age, wood-feed speed, and wood-cut depth. Additionally, noise emanating from both types of SSIs was found to influence the level of environmental noise in the neighborhood of the SSIs. One woodworks SSI was found to have a circle of influence of about 140 m. The study concluded that SSIs present a serious source of environmental noise pollution in their neighborhoods. Noise pollution from SSIs is greatly influenced by the type of SSIs and the activities they carry out, the type and age of machines they use, their location relative to residential areas in their vicinity, and in-house noise control measures. 相似文献

The impact of visual factors on noise annoyance among people living in the vicinity of wind turbines 总被引:1,自引:0,他引:1
Wind turbines are highly visible objects and the response to wind turbine noise is possibly influenced by visual factors. In this study, visibility of the noise source, visual attitude and vertical visual angle (VVA) in different landscapes were explored. Data from two cross-sectional field studies carried out among people living near wind turbines (n=1095) were used for structural equation modelling. A proposed model of the influence of visual attitude on noise annoyance, also comprising the influence of noise level and general attitude, was tested among respondents who could see vs. respondents who could not see wind turbines from their homes, living in flat vs. hilly/rocky terrain, and living in built-up vs. rural areas. Visual attitude towards the noise source was associated with noise annoyance to different degrees in different situations. A negative visual attitude, more than multi-modal effects between auditory and visual stimulation, enhanced the risk for noise annoyance and possibly also prevented psychophysiological restoration possibilities. Aesthetic evaluations of the noise source should be taken into account when exploring response to environmental noise. 相似文献
