Status of Noise pollution Bangladesh Scenario -Zannatul Mouwa Naz and Mahmud Kamal Anamul Haque
The balance of the environment on earth has been maintained for a long time. Plants and fauna have been shown to adapt to the changing environment of the world. The reason for the survival of the earth is that the earth has a lot of air and water supply. And there is the temperature here. Every day people are benefiting in many ways from the sky, air, plants, soil and sunlight of this world. If any of them decreases or increases, it will become impossible for human life to survive on earth.
Various pollutants created by nature and human society destroy the rules of weather and natural balance. It creates an unhealthy environment that has a detrimental effect on the birth and growth of the earth’s flora and fauna. Environmental pollution can be of different types, such as air pollution, water pollution, soil pollution, noise pollution, etc. Noise pollution is a big problem. Whenever noise is annoying and harmful it goes to the stage of pollution. Noise pollution is a widespread occupational health problem.
Along with economic development, on the one hand, as environmental pollution increases, on the other hand, people’s awareness of improved lifestyle increases. Environmental pollution usually increases in the early stages of development. This is due to higher production and consumption which puts more pressure on the environment and causes pollution. We communicate with each other through conversation. We hear the words of a person through our hearing cells. But we hear a certain level of sound,louder and more low sound we do not hear. Noise pollution is diagnosed depending on the intensity of the noise. The unit of sound size is decibels. We hear sounds from 20 decibels to 120 decibels. I can’t hear low decibels at 20 decibels and high decibels at 120 decibels. However, normal human hearing is 60-65 decibels. As soon as the noise level exceeds 65 decibels, it falls into the stage of noise pollution. It has now been proven that not only objects pollute the environment, objects can also pollute the environment such as noise. Noise pollution is a loud and unwanted noise that upsets the balance between the environment and humans or any other organism.
The consequences of noise pollution are not immediately understood. It usually affects the human body indirectly and gradually. Noise pollution can be caused by a variety of factors, including loud horns of vehicles, factory noise, noise of various construction works, noise of vehicles moving, uncontrolled loudspeakers, noise of aircraft, location of mills in residential areas, loud noise etc. The level of noise pollution is much higher in urban areas than in rural areas.
Ordinary people do not understand how sound pollution can be and how devastating it can be to the living world, including humans. So around us we constantly cause noise pollution. An example is noise pollution from various sources in Dhaka city. The average noise level in Dhaka city is above 100 decibels. The noise levels of stone crushing machines and jet engines are 120 and 130 decibels, respectively. The noise level of the short gun is 140 decibels. Noise levels in markets and factories, tractors and new motor vehicles are 90-100 decibels, 60-70 decibels and 95 decibels respectively. Of course, noise pollution can be caused not only by the workplace or outside the home, but also by modern appliances used in the home, such as vacuum cleaners, food benders, dishwashers, food grinders, television loudspeakers, fans, etc. According to a study, if current levels of noise pollution continue, one-third of the world’s population will be affected by 2023. They may be deaf, but they may also have heart problems, including loss of appetite, high blood pressure, inability to concentrate, and ringing in the ears. There is no direct research on this in Bangladesh A 2016 study found that one-third of people were directly affected There is more or less damage in it Not everyone is being harmed in the same way Someone is getting more, someone is getting less loss However, the loss is 6 for everyone
Noise pollution can cause mental and physical discomfort to people. Noise pollution disrupts blood pressure and heart rate, reduces hearing, and even deafness. Noise pollution can lead to inflammation of the larynx, ulcers, and various diseases of the brain. Sudden loud noises, such as the sound of bombs or crackers, sharp hydraulic horns of vehicles adversely affect the human veins and nervous system. This type of noise can temporarily stop the flow of blood. Depending on the intensity of the sound, different reactions may occur in different people, such as annoyance, irritability, emotional turmoil, and even adverse effects on the environment. Noise pollution is one of the major causes of mental illness in Bangladesh. In Paris, France, 80 percent of neurosis patients are affected by noise pollution. One million children in the United States are addicted to rock music and suffer from deafness due to noise pollution. Noise pollution can cause physical and emotional damage to the fetus, and even death.
Noise pollution harms other biological and inorganic elements of the environment besides humans. It is difficult to find any living community other than human beings in Dhaka city. Apart from a few plants, small birds, street dogs, cats, rats and mosquitoes, no other fauna can be found here. Only Allahknows the condition of these small living beings due to the deadly noise pollution in Dhaka city. Again, since sound is a kind of vibration, the sound of high vibrations also destroys the balance of inorganic elements in the environment.
The first thing that is important in controlling noise pollution is to regularly measure the noise level from various vehicles and mills and to ensure appropriate punishment against loud noise producing vehicles and mills. Although developed countries have regular measures to measure noise levels from various mills, our country has not yet taken any such step, which is very important. Sub-paragraphof section 25 of the Dhaka Metropolitan Police Ordinance 198 states that the police shall not be allowed to disturb or disturb the public or nearby residents by using hydraulic horns, loud music, musical instruments, drum beats etc. in vehicles on the road or in public places. The commissioner can impose any kind of punishment as per the rules including immediate arrest. But the proper implementation of this law has not been started yet. Of this law Must confirm application. Section 15, Sub-section 1 of the Environmental Pollution Protection Act, 1995 states that if a person violates the provisions of this Act or fails to perform his duties or comply with the notice or notice given under this Act or Rules, he shall be liable for similar failure. Imprisonment for a term not exceeding 5 years or a fine not exceeding Rs. 1.0 lakhs or both. It is to be noted that the word has also been described as an environmental polluter in the said Act. It is very important to ensure proper implementation of this law.
In addition to following the above methods, there is a need to create public awareness about the harmful effects of noise pollution. Those who cause noise pollution by sounding unnecessary horns on the roads should be made aware. When one realizes that the car horn is really harmful then at least he will not blow the horn unnecessarily. Awareness is also important in controlling the use of loud microphones. And only we can control the noise pollution in our house. In this case too, the awareness of the individual is the only hope.
