[Computer simulation model of propagation and impact of undergroud garage noise between buildings in urban residential region].

Aimed at certain types of building dispositions in urban residential region, the noise impacts of the underground garage is analyzed and calculated with the simulation model of random point sound source. The comparison between the predicted results and measured value of noise level shows that the predicted model presents an acceptable degree of accuracy. Adopting this model to predict noise impacts of the underground garage in designed and newly-built residential region will provide scientific basis for effective noise
