Description :
Noise is an unwanted sound which feels discomfort to the ears. Noise is also considered the most
dangerous pollution like air and water pollution. Along with water and air pollution, noise pollution is
also emerging as a new threat to the residents of the city. Noise pollution caused by vehicles which is
affecting the environment and quality of life directly and indirectly. Noise pollution can be considered
as one of the main concerns of the world, especially in urban areas. Vehicular traffic is one of the major
sources of noise pollution in urban areas. In the present study, the monitoring of noise level was carried
out for the assessment of noise pollution levels at selected sites Chowk, Jhonstonganj and Civil lines
during January, 2017 in Prayagraj (Allahabad). The monitored data were used to calculate various noise
parameters, namely percentile noise level L10 and L90, equivalent constant level (Leq), noise pollution
level (Lnp). The L10 were observed in the range between 78.00-90.68 dB, 73.40-91.70 dB, 78.24-89.74
dB and L90 60.80-72.82 dB, 54.94-75.54 dB, 63.06-74.66 dB with Leq values 74.59-87.36 dB, 70.15-
88.20 dB, 74.69-86.23 dB and Lnp values 91.79-105.30 dB, 88.61-105.92 dB and 89.71-102.23dB
respectively at Chowk, Jhonstonganj and Civil lines. The results of the study revealed that most of the
times Leq values were higher than the permissible limits as per CPCB standards. The higher values of
Lnp indicate the possibilities of physiological and psychological problems caused by noise pollutions at
various places in Prayagraj (Allahabad) city. The higher noise levels are mainly due to movement of
vehicles, vehicular jams and pressure horns.
