4. CONCLUSION
The study reveals the spatio-temporal distribution of noise, generated by urban traffic, by means of monitoring,
mapping and questionnaire as a tool for evaluation of impact. The quantified data shows that the city is exposed to
noise levels ranging mostly from the moderate to extremely high levels in comparison to the national standards.
Immediate administrative and technological mitigative measures should be adopted at the earliest to prevent auditory
and non-auditory health impacts on the local population. Control methodologies can include control of noise at
source of generation. Control in the transmission path by installation of barriers between noise source and receiver
can attenuate the noise levels. The barrier may be either close to the source or receiver. The design of the building
along with the use of suitable noise absorbing material for wall/door/window/ceiling will reduce the noise levels.
Other measures include raising the awareness among local community, locating more No Horn zones and strict
enforcement of laws.
The results can be considered as not being acquainted with the environmental noise. However, it was demonstrated
that this phenomena had some effects on the personal characteristics and nervousness of the individuals as social
consequences. Therefore importance of noise controlling management should be taken into considerations. As a
solution to all the harmful problems caused by the traffic noise, it is necessary for these people to undergo periodical
checkups to eliminate late diagnosis of hearing capability loss and problems in the mental and nerve systems.
Finally, the municipal management must have special noise management planning in metropolises like Ghaziabad;
constructing shopping centers & entertainment venues with appropriate and equal costs at diversified location so that
traffics for shopping & entertainment purposes would decrease; making e-commerce popularized; optimizing public
transportation system with adequate capacity. The induction of batteries operated vehicles will also lead to reduce the
noise level.
