中文摘要: |
本文为研究机动车噪声源强与速度、加速度的关系,对车辆在不同速度和加速度下的A计权声压级进行测试,运用统计学方法对测试数据进行分析,得到机动车单车噪声源强与车辆速度、加速度的关系模型,并与《公路建设项目环境影响评价规范(JTG B03-2006)》中的交通噪声源强预测模型进行比较,实测验证结果表明,利用本研究建立的机动车单车噪声源强模型所得预测结果更符合实际。 |
英文摘要: |
In this research, the A-weight sound press levels of vehicles under different velocities and accelerations are tested to study the relationship between the noise source intensity and the velocity and acceleration of vehicles. The emission model of vehicle’s noise source is obtained using the method of statistical principle based on the testing data. And then this model and the vehicle’s noise source intensity prediction model in Specifications for Environmental Impact Assessment of Highways(JTG B03-2006) are compared using the other measured data. It is proven that the vehicle’s noise source intensity prediction model which is set up by this research is much closer to the actual situation. |
