科研大楼环境噪声影响评价及控制研究

Impact Assessment and Control of Environmental Noise in Scientific Research Building

舒适安静的工作环境是科研工作人员必备的条件,创造一个良好的声环境工作氛围,既能加快科研成果研发进度又能提高产品研发水平。文章以某公司研发大楼为例,利用Noise System模型重点研究了周边环境噪声在其垂直方向上的变化规律。预测结果表明,研发大楼各侧5层以下(1~15 m)处于声影区、5层以上(15~70 m)处于声照区,并且在5~7层之间噪声值有突变现象;Leq(A)随高度增加呈增加的趋势。

A quiet and comfortable working environment is the necessary conditions for personnel of scientific research work, and create a good atmosphere of acoustic environment, which can speed up the progress of scientific research and im-prove the product research and development. In this paper, scientific research building a company as an example, the study on variation rules of surrounding environment noise in the vertical direction by using the Noise System model focused on. The predicted results show that, the side building 5 layer below(1~15 m) in the acoustic shadow, more than 5 layers(15~70 m) in the irradiated area, and the noise of 5~7 layers have mutation phenomenon; Leq(A) showed an increasing trend with the increase in height.
