Even though the daily minimum noise level at all locations is more than db(A), which clearly reflects the gravity of the problem on the roads of the major cities of Pakistan. The highest maximum noise level db(A) was recorded near the Piranha General Bus Terminal, the hub of inter-city and intra- city heavy traffic. At the said location, the daily equivalent noise level 97. 1 db(A) was calculated from the daily recorded maximum and minimum noise levels. The daily noise figure at the location is extremely higher than the NEWS permissible limit, mints out the study carried out under the Pakistan Environment programmer.
The study urged the law enforcement agencies and regulatory bodies to pay attention to the problem and bring down the figure for the betterment of the passengers and nearby areas. The second highest noisy location was spotted near Churl Chock, on Appeaser Road in Rawlins, where the daily maximum level was db(A). Bank Road in Sad and Melody Road Barbara Chock were found less noisy locations. At these locations, the daily equivalent noise levels were within the permissible limits of NEWS, reveals the study.
According to the study, in comparison to other pollutants, the control of environmental noise has been hampered by insufficient knowledge of its effects on humans. The report concludes that once traffic noise is recognized as a serious issue in sustainable transport planning, the traffic noise could be tackled through a seven parts strategy which includes removal of pressure horns from the public transport; setting standards; motor vehicles control; land use control: traffic management; surface design and maintenance; and road geometry and design.
