| Abstract: | The prediction theory of sound radiated at tunnel openings about Cadna/A acoustic software are introduced detailly.The effect of sound radiated at tunnel openings is being simplified as simple vertical area source related tunnel openings shape.It is more easer to use tunnel parameters to calculate the sound power level of simple vertical area source.By the example and demo,the author offers some reference on how to accurately use the software to predict noisy and for environmental impact assessment of same projects. |
