This document summarizes a study that measured noise pollution levels on Jail Road in Faisalabad, Pakistan over the course of a week. Noise levels were measured using a sound meter app at a distance of 25 feet from the road center. Noise levels ranged from a low of 68.3 dB on Wednesday to a high of 75.5 dB on Thursday. High noise pollution can cause health issues like hearing loss and sleeplessness. The conclusions determined that the sound quality on Jail Road was very disturbing due to heavy traffic from over 1 million vehicles registered in Pakistan and 84,674 in Faisalabad alone.

MEASUREMENT OF NOISE
LEVEL IN ENVIRONMENT:
JAIL ROAD
Group-3
SEE-503 Fundamentals of Environmental Engineering

2. Objective:
To measure the pollution produce
due to sound and its effect on
surroundings specially on humans.

3. Introduction:
An ecological imbalance among the
constituents of the environment causes
environmental pollution. When sound
level increases beyond the permissible
limits, it causes noise pollution and traffic
is one of the sources of noise pollution. An
increase in traffic density at the roads
enhances the noise level, and adds to the
noise pollution.

4. MATERIALAND METHODS:
Jail Road Faisalabad is selected as site
to check noise level.
A sound level application “sound
meter” downloaded by app store set is
used to measure the noise level.
The noise was measured at a distance
of 25 feet from the center of the road.

10. Highest and Lowest Values:
We note highest value on Thursday
which is 75.5 dB while lowest value
on Wednesday which is 68.3 dB

11. Effect on Health:
The health effect of noise is auditory
damage, which includes in hearing loss.
This is frequently caused by heavy
traffic noise. In this way, noise pollution
also causes sleeplessness, vegetative
hormonal reaction and damage of
hearing organs.

12. Conclusions:
 We performed this experiment at jail road
and found out that the sound quality was very
disturbing there.
 According to the local survey there were
1,044,837 vehicles registered in eight months
in Pakistan. In Faisalabad 84,674 vehicle
were registered. Such heavy traffic causes
enormous noise pollution, which results in
annoyance, discomfort and trouble and even
fear or limitation in the behavior.
