This study evaluated the impact of urban road traffic noise on roadside schools, colleges, hospitals, and a court through both in-field measurements and an on-site questionnaire survey. It demonstrates that there are problems and non-compliance, and that the high levels of noise cause annoyance. Three secondary schools, three colleges, three hospitals, and one court building designated as a silence zone under CPCB standards were targeted, located near various roads in the Surat city in Western India. Noise levels were measured within the 100 m of silence zone. The results demonstrated that noise pollution at roadside schools, colleges, and hospitals was reasonably severe, school and college noise levels considerably correlated with the road traffic noise. The study area's equivalent noise level was 79.0 dBA, and the maximum noise level across all ten roads is 111.6 dB (A). During the evening (peak) hours, the road is a flexible pavement (Dumas-Athwa line Road). The minimum noise level measured across all ten location roads is 48.4 dB (A). It is during the evening hours at Lancer army school road. The difference between the maximum and minimum noise levels is very high at all locations. The minimum noise level is still more significant than the permissible noise level of 50 dB (A) across all locations. The on-site questionnaires revealed that people in this area, students, lawyers, and teachers, felt disturbed by the road traffic noise, and that the intensity of disturbance increased with the increase in traffic levels.
