Propagation of Noise in Urban Environments

With the growing population in the urban areas and the constant construction and design projects executed in these sites, noise has become quite a big issue. Noise pollution and its impact on the people have increased a lot over the past few decades. One of the common causes of extreme noise pollution in urban areas is ineffective urban planning. Besides, the increased use of motor vehicles in urban areas has led to environmental problems. Noise community ordinances have established noise limits for different zones. Noise pollution can be more problematic and difficult to manage than other kinds of pollution for the environment. Plus, it can have a very serious impact on the environment. It has become more important, now than ever, to mark the areas prone to noise pollution. Usually, these are places that receive high motor traffic or construction sites where different kinds of equipment are used regularly. Anything that causes noise higher than the standard sound can lead to noise pollution in an urban environment. GIS has often played an important role in identifying the leading sources of noise pollution and managing these sources. The main purpose of using noise pollution control measures is to know about the locations that contribute to noise pollution and take effective measures to control the pollution. The well-being of people and protection of the buildings have always been important for the management of noise in urban environments. With the help of land-use planning combined with other geospatial analyses, it is possible to develop an effective noise management program. How can Noise Pollution be Controlled After Detection? Once you have identified the areas producing high noise, the next step is to reduce the noise level as much as possible. The goal is to reduce the noise to the lowest achievable level, especially when there’s a possibility that somebody’s health could be affected by high noise levels. Effective measures should be taken to protect the public’s health. If the best standards of noise control management are not achieved, you need to implement the best noise control tactics to revise these strategies. The right noise pollution management techniques must be in place for smart and effective management. In most cases, you might see that noise pollution is incredibly higher than certain guidelines. Noise standards, for any given area, might change significantly over time. The main purpose of using GIS for noise detection in urban environments is to identify the areas affected by noise pollution, the source of that noise, and the type of people affected. You can assess the noise in different ways, but the most popular option is noise mapping. The objective of conducting noise assessment in different areas is to assess noise from various sources, figure out the expected level of noise, and map these noise levels. The common source of noise is often transportation vehicles. The vehicles stuck in high traffic, horns, music, and other factors can contribute to the growing noise pollution in the city.
