This study is aimed at bringing out the salient
aspects of urban noise and its study and control aspects, at different
location of a metropolitans town. Field measurements at different points
of times a day have also been recorded at a number of
high-traffic-intensity locations on main roads of towns. The data
obtained are analyzed using SPSS package for calculation through ANOVA
technique and the findings of these studies have been recorded. The
variation of SPL considering the time of the day has been studied and
illustrated through graphical plots. It shows that the peak early
morning max sound pressure levels observed over the recommended limiting
value. In some places, the low frequency noise predominates in the
early morning hours, noise levels are significant among and within the
15 groups. The variation of sound pressure (Maximum, Minimum and L
equivalent readings) levels as shown in the graphical plots, the Maximum
and L equivalent levels exceeded the recommended noise level. Important
conclusions of this work have been drawn subsequently.
