【Abstract】 The model of random point sound source was applied to predict the noise of underground garage in urban residential region with the method of computer simulating. Comparing the predict data and the data of measurement, the precision of this model was good. The model can be applied to predict the influence of the noise of new built underground garage noise, it can offer the reference for the planning department.更多还原
