This plan analyzed the noise complaint cases in recent years, and compared social and economic factors such as population, land area etc. for correlation analysis. When analyzing the six metropolitan areas, it can be observed that there is a high correlation between the number of people and the number of noise cases. The number of people has a direct relationship with the number of cases. The remaining counties may be less relevant because of the densely populated areas. Investigated 6 cases of repeated noise cases, and found that in most cases, the location was a mixed type of residence and business use. When business equipment was running, the noise transmitted through the building structure, and while the low background environment noise existed, it often occurred the people to feel the noise. The data of noise monitoring stations in four municipalities such as Taipei City, New Taipei City, Taichung City, and Taoyuan City were summarized, the trend of changes was analyzed and a colored histogram was made for comparison. It also compares the information of the common report sections of the four municipalities with the results of environmental and traffic volume monitoring. This plan also collected and compared the duties and responsibilities of the ambient countries or regions in the noise control or management department, summarized and extracted the relevant content of the noise project of the environmental impact assessment monitoring report, and put forward relevant recommendations to combine with the noise control affairs.
