SPATIAL PATTERNS OF NOISE POLLUTION AND ITS EFF...

Lahore is one of the cities most effected by uncontrolled noise pollution in Pakistan. The most
important factor of noise pollution is the road traffic. The main objective of this study was
to analyze and evaluate road traffic noise and to measure its effects on the population of
Lahore city. A weighting sound level meter was used in the study. All the measurements were
taken at a height of about 1.2 m from the ground at 56 sample sites. The spatial noise pattern
was shown in maps. These were also drawn to show buffers dividing areas into moderate  high and
extremely high risk zones in accordance with noise risk levels. The maps were additionally
divided in day and night time maps  each with graduated symbols. The main day-night values were
exceeding the permissible environmental standards used in Pakistan. Therefore  a survey was
conducted to study the diseases caused by noise pollution in the areas with highest noise
levels.
