以Cadna/A噪声计算模式为基础,建立基于Cadna/A软件的高速公路噪声预测模型,对某拟建高速公路沿线噪声敏感区的声环境质量进行预测,并预测和分析声屏障设置后的噪声敏感点声环境质量状况,为高速公路噪声污染防治提供依据。
Based on the Cadna / A noise model, the highway noise prediction model based on Cadna / A software is established to predict the acoustic environment quality of the noise sensitive area along a proposed expressway and the noise after the noise barrier is predicted and analyzed Sensitive point of the sound quality of the environment for the highway noise pollution prevention provide the basis.
