Noise Mapping of Ambathur Industrial Estate Junction Using GIS

Noise from vehicles contributes to the high pollution levels in several spots of Indian cities. The development of a city leads to the rapid growth of the number of vehicles which is directly leads to increased traffic congestion and traffic noise. In this study a GIS based noise assessment was carried out at Chennai city in Ambattur, an industrial zone. A digital sound level meter is used for assessment of noise level. Noise mapping was done using Geographic information system (GIS) technique. This approach helps to assess the noise levels to which people are exposed and monitor the impact of noise. The spatial analysis and geo statistical methods of GIS can play an important role to control noise pollution. GIS provide framework to integrate noise calculation models with spatial data that can be used for building noise maps. The variation in the noise levels and traffic volume data in the peak hours are studied and presented as noise map for the selected location. This study also includes the effects and remedies which can be provided for minimizing the noise pollution.
