Abstract :This study was conducted of traffic noise which affected on urban traffic noise of selected roadside school as acoustic comfort for selected locations insert ignore into journalissuearticles values(near school buildings); of Burdwan town and the ambient noise was recorded during four different time periods insert ignore into journalissuearticles values(early morning, late morning, afternoon and evening);. Geographical Information System insert ignore into journalissuearticles values(GIS); based Inverse distance weighting insert ignore into journalissuearticles values(IDW); interpolating technique was used to identify the vulnerability of noise pollution in mixed areas of schools. The different acoustic descriptor such as Leq, L90, L50, L10, noise climate insert ignore into journalissuearticles values(NC);, traffic noise index insert ignore into journalissuearticles values(TNI); and noise pollution level insert ignore into journalissuearticles values(NPL); were evaluated, while a community study was also simultaneously conducted. The results revealed that the average Leq, L90, L50, L10 varied from 76.5 dB insert ignore into journalissuearticles values(A); to 78.6 dB insert ignore into journalissuearticles values(A);, 58.2 dB insert ignore into journalissuearticles values(A); to 60 dB insert ignore into journalissuearticles values(A);, 65.6 insert ignore into journalissuearticles values(A); to 67.3 dB insert ignore into journalissuearticles values(A); and 86.6 insert ignore into journalissuearticles values(A); to 94.5 dB insert ignore into journalissuearticles values(A);, respectively. It was observed that the noise climate reached its peak in the afternoon insert ignore into journalissuearticles values(35.7 ± dB insert ignore into journalissuearticles values(A);); and was the lowest in the evening insert ignore into journalissuearticles values(27.8 ± dB insert ignore into journalissuearticles values(A););. The health data indicated that about 71% and 8% of the inhabitants near the schools were suffering from irritation and sleeping problems respectively. The similar correlation study revealed that Leq insert ignore into journalissuearticles values(r = 0.484, p < 0.679);, L90 insert ignore into journalissuearticles values(r = 0.871, p < 0.327);, and L50 insert ignore into journalissuearticles values(r = 0.507, p < 0.662); were strongly correlated with sleep disturbance. It may therefore be safely concluded that school children in the subject schools being exposed to the same levels of hazard as the residents in the immediate vicinity were probably suffering from similar problems.
