| The issue of optimization of points distribution of noise measurement in enclosed street plays an important role in improving the efficiency of the noise measuring. Based on the genetic algorithm and with noise analysis software, this paper builds an optimized model of distribution of noise measuring points. With this model, the optimized measurement points with the least number of measuring points and of the least deviation from the original point can be determined from large number of noise points. Then the optimized model is applied to a specific enclosed street, and the optimal distribution of the measuring points is searched out. The results show that the model can be used to reduce the number of noise points without weakening the accuracy and thus it provides a theoretical basis for the noise measurement in the future.
