| 围蔽街道噪声测点优化布置的问题对提高噪声测点效率有着重要影响。本文基于遗传算法并运用噪声分析软件，建立了一种噪声测点布置的优化模型。该模型从大量噪声测点中搜索出测点数目最少且与原测点偏离较少的优化测点。然后将该优化模型应用于某一特定围蔽街道，搜索出该街道的最优测点布置方式。结果显示该模型在不影响精度的情况下可减少噪声测点数目，为今后街道噪声测量提供理论依据。 |

| 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. |
