| 中文摘要: |
| 以崇明越江通道工程环保验收噪声监测为例，通过所取得的声断面衰减的监测结果与采用《环境影响评价技术导则 声环境》（HJ 2.4-2009）推荐模式和德国Cadna/A环境噪声模拟软件得出的多个预测结果进行对比，提出了虽然现行的环境影响评价技术导则模式和Cadna/A软件在进行噪声预测时具有较好一致性，但在考虑地面建筑物对声音的衰减时，两种预测方法得出的结果都较为保守，建议应结合GB/T 17247.2的地面衰减计算公式进行修正。 |
| 英文摘要: |
| By taking the environmental protection engineering inspection of Chongming Tunnel as an example, and by studying the monitoring results of the noise section in Chongming Tunnel, and by comparing the proposed module of “Technical Guidelines for Environmental Impact Assessment” with the predicting results made by Germany Cadna/a Ambient Noise Simulation Software, research work indicated that although nowadays technical guidelines for environmental impact assessment and Cadna/A had a good conformance at predicting noise levels but these two prediction methods were still relatively conservative if ground structures caused sound decrease. Suggestion was made for combining the national standard “GB/T 17247.2 Acoustics——Attenuation of sound during propagation outdoors——Part 2: General method of calculation” to correct the computed results. |
