Md. Atikur Rahman :
Environment pollution has reached an unbearable level. In many ways our environment is being polluted. One of the main causes of environmental pollution is noise pollution. At present, the condition of noise pollution in Dhaka city is very alarming. It seems to be a problem, but because of our unconsciousness we often say that it cannot be resolved. But these problems are made by humans. If we adopt a little awareness then it is possible to control this problem. Noise pollution also affects heart, blood circulation, food canal and stomach besides causing some mental complications, according to psychiatrists and cardiologists. People of different ages also suffer from various diseases because of this pollution in Dhaka city. Sometimes intolerable sound pollution may cause death to ischemic heart patients.
Sound control is one of the constraints of environmental pollution. At home, in the office, on the streets and even in recreation, we are being subjected to noise pollution in a number of ways. Worldwide, people have the right to prevent environmental pollution. In Bangladesh, the issue of prevention of environmental pollution is also a matter of concern. Many people are working for the development of public awareness and environmental development in order to preserve the environment. The media will have to move forward in this regard.
According to World Health Organisation (WHO), the safe limit of sound is 45 decibels. Sound over 65 decibels creates heart diseases and over 90 decibels of sound leads to ulcer, hearing problems and changes of nerve system and that of over 120 decibels creates pain in the ears and destroys hearing ability gradually.
According to a study of BUET on noise pollution, 45 decibels of sound was around the city in 1985 which was tolerable, but in 1990 it rose to 55, in 2000 it was 75 and in 2013 it rose to 110 decibels to some of the areas. On average, 105 decibels of sound is created in Dhaka city everyday which is alarming and a permanent health hazard to the city dwellers. The study also says high-pitched sound of hydraulic horns of buses, trucks, private cars and even motorcycles, cassette players in the market and buses, loud speakers and roadside mills and factories severely affect passengers and passers-by. Noise pollution around Dhaka city is increasing day by day due to growing number of public private vehicles.
Recently the use of polythene shopping bags was announced by the government’s positive steps for the promotion of public interest and environment. Which has had significant impact in social life? Private organizations and media have come forward and have played an important role in making it effective. At present, air pollution-prevention of water pollution and a forestation issues are discussed, but only the limited constraints of discussion or thinking about noise pollution.
There is no clear idea among the public about noise pollution due to severe health problems. Although several non-governmental organizations have some work on this, it is very little compared to the problem. There is no law in our country to control noise pollution; traffic laws are not being properly observed. Work for a Better Bangladesh is working to control the control of noise pollution including the control of tobacco control, air pollution, and limiting the use of polythene bags.
Our recommendations have been presented in this report by taking the public opinion about some of the fundamental issues related to noise pollution and controlling it, which we believe is important for increasing public awareness and determining government policies. Those organizations or individuals, who are interested in working with noise pollution, hope they will benefit from this report. We believe that the guidance given by the increase in public awareness and unified action efforts of government non-governmental organizations will help to take sound pollution to the level of control.
We can easily follow the methods of preventing pollution:
If we are a little aware of ourselves, we can protect ourselves from being polluted; Give the volume of the TV and music system used at home. Do not play car horns unusually unnecessarily. Do not use loudspeakers. Playing the band in the wedding procession, stop-cracking crackers. Talk about complying with all the noise pollution laws.
Use organic fertilizers instead of chemical fertilizers. Use paper instead of polythene. Use cotton and jute instead of polyester. Arrange the polythene bag properly. Add more trees and plants. Regarding compliance with all laws related to chemical pollution. Electronic pollution in the whole world has been horrific. Extraction of pollutants from digital or electronics is used to throw away or use. Sometimes the virus is infected by this pollution.
That’s a great challenge to save a new computer or digital gazette. To avoid this, different companies employ other companies to remove such contaminated waste. In India, only a few companies are working to stop digital pollution. It is seen, Mumbai, after Bangalore, the most electronic pollution is in Calcutta. But hopefully the awareness of this pollution is increasing.
Sound pollution across the country including the capital has now reached a critical level. Therefore, it is now referred to as ‘word terrorism’, expressing solidarity with the demand of Environmental Organizations, 13-point demand, including sound pollution prevention law, Bastian. Because noise pollution is now life-threatening terrorism; It is important to protect our environment and public health in deep crisis.
At present, the level of noise pollutants from different parts of Dhaka city ranges from 80 decibels to 110 decibels. In some places it even more.
This level is growing with time. In the vehicle, the use of high level noise sound, heavy hydraulic horn use, construction noise, brick-kiln machine, besides yellowing, marriage, fertility, birthdays, New Year, high sound effects, and high sound sounds are being terrorized. As a result, due to noise pollution, the hearing loss of the people is decreasing, sleeping at night, heartburn and new cardiovascular disease, decreasing performance and severe harm to students’ education. So this word terrorism must be stopped at any price.
In the end, I want to say that the implementation of the Sound Pollution Control Act, the law enforcement agencies form a mobile team, identify the sound terrorists, take legal action, stop construction of any kind of noise making work including construction of residential areas at night, ensure that there is no higher horn in the car, unnecessary horn If it is possible to train and alert the drivers about not using them. Everybody to work together to reduce the noise level so that in the long run people can eradicate noise pollution from the country once for all with awareness of all is more important.
