A Review on Environmental Impact Assessment on Noise Environment

Noise is defined as an irregular and disorderly sound with strong and weak changes that has many adverse effects on people and the surrounding environment and is one of the forms of environmental pollution.Possible sources of noise include aircraft, automobiles, factories, construction sites, daily life, etc. Countries generally use environmental impact assessment (EIA) to assess the impact of noise generated by activities in different fields on the quality of the surrounding environment, to predict the extent and population affected by environmental noise for the next step in controlling it to prevent harm to people and the environment.Different countries' standards, methods, and technologies for assessing the environmental impact of noise may be similar, the same, or different during the assessment process.In this report, through a great deal of Internet searching for related academic papers and online consultation with some environmental assessment institutions, Review the theoretical knowledge of technical methods of environmental impact assessment in a noise environment, and discuss and analyse the advantages and disadvantages.The results show that the statistical method and the average method are common but require a lot of manpower and resources.The fuzzy mathematics evaluation method needs a lot of accurate calculation and requires high-quality personnel.The data in the noise map is intuitive and comprehensive, but the basic workload is large.Each method has its advantages and disadvantages, and the choice depends on the situation.
