Noise Pollution is used to define an undesirable and unwanted sound that is often louder than what our ears could happily receive. There are many sources of noise pollution found in our houses and outside. Noise pollution is more prominent in urban areas as compared to rural areas. In the following essays, we will discuss everything about noise pollution including its effects on humans and other life forms.

Essay 1 (300 Words) - Effects and Control of Noise Pollution
Whenever the sound level in our surroundings becomes noise, exceeding the permissible limit, the term noise pollution is used. The intensity of sound is measured in decibels (dB) and any sound measured around 70 dB isn’t considered a noise. But, any sound above 70 to 75 dB is considered noise as it has severe consequences on human health and the ecosystem. In the below essay we will discuss the effects of noise pollution on human health and also some measures to control noise pollution.
Effects of Noise pollution on Human Health
Noise pollution has many severe effects on human health like sleeplessness, lack of concentration and performance degradation, stress, cardiovascular disease, etc. People who live in the proximity of noisy areas are unable to get sound sleep and are often irritated and stressed. Prolong exposure to noise could have a severe psychiatric effect on an individual.
Effect of Noise Pollution on Animals
Noise pollution also disturbs the environment as it scares away the animals and birds from a particular area, disturbing the ecological balance. Birds and animals get scared and disoriented due to noise and leave their resting place in haste and fear. Animals don’t understand the reason behind the loud noise as humans can and thus become very vulnerable to get confused and disoriented.
How to Control Noise Pollution?
Controlling noise pollution in some cases could be really easy while in others a daunting exercise. You can bring down the noise level of your neighborhood by taking some simple steps in your own house, like keeping the volume of your television and music system low, just enough to let you hear; avoiding unnecessary use of machinery, drill, etc in the house; ensuring that the privacy and peacefulness of your neighbors are maintained during celebratory events in your house.
Noise pollution has severe impacts on human health as well as on the environment, animals, and birds. Its health impacts on humans include both physical and psychological effects. Either humans or animals, when subjected to persistent noise pollution, could suffer from severe trauma, sometimes resulting in serious physical and mental disturbances.
Essay 2 (400 Words) - Places where Noise Pollution Booms
When the decibel (dB) level of sound in an area passes the permissible limit (70 dB) it is usually referred to as “noise pollution”. Noise pollution has become a growing concern for human health as well as for the environment. In this essay, we will discuss some of the noise pollution examples.
Examples of Noise Pollution – Places where Noise Pollution Booms
Some of the most common examples of noise pollution are described below:
1) Construction Site
Construction sites are a very significant example of noise pollution. A busy construction site uses heavy and noise-generating machinery, all at the same time. Simultaneous use of several types of equipment at the same time generates noise that is much beyond the permissible limit.
Airports are other good examples of noise pollution. Engine noise and other mechanical noises coupled with aerodynamic noise generated by an aircraft during takeoff could easily reach up to 140 dB. The noise generated by the rotating fan blades of an aircraft when they reach supersonic speed could be deafening and disturbing for those living in the vicinity of an airport.
3) Roads and Highways
Busy roads and highways are some other examples of noise pollution. The vehicular movement on a road constitutes all kinds of vehicles – motorbikes, cars, trucks, buses, etc. Together, they generate noise beyond the permissible limit. Let’s also not forget the noise generated by honking and blowing horns. Highways are 24/7 busy with heavy traffic and huge transport vehicles and are a perfect example of noise pollution for any person residing in the vicinity of a highway.
4) Public Events and Concerts
Large public gatherings as in marriage functions, religious congregations, football matches, cricket matches, etc are also some of the most significant examples of the places with noise pollution. For example, a religious event has too many people gathering at a place resulting in crowd. Also, there are several other activities like chanting, singing, and fairs are carried out simultaneously, thereby generating noise.
The sources of noise pollution are many and almost all of them constitute human activities of some form or the other. In some cases, noise could be considerably reduced by taking minor steps while in others it may require a collective effort and will to do so. Sometimes, to tackle noise pollution there might arise a need to make policy changes and to implement strict guidelines. Whatever the case may be, the capacity to bring a change is only in the hands of humans.
Essay 3 (500 Words) - Sources and Control of Noise Pollution
“Noise Pollution” refers to the extension of noise in the environment we live in. It is also called sound pollution. Noise pollution is mainly caused due to human activities like transportation, construction work, heavy machineries, and urban settlements. The gravity of noise pollution and its effects on humans and the environment is often neglected.
Sources of Noise Pollution
Potentially harmful noise could be generated by many sources. Below we will discuss some of the vital sources of noise pollution.
Transportation is one of the main sources of noise pollution all over the world. Engine noise, horns, exhaust noise of autos, light motor vehicles, trucks, buses, etc generate constant noise pollution. During traffic jams or in narrow lanes, noise pollution becomes so prominent that sometimes it becomes difficult to hear one’s own voice. A busy road or high has a noise pollution level around 90 dB (decibel) or above against the permissible limit of 70 dB.
2) Construction Work
Construction work uses many types of machineries like – drill machines, bulldozers, transport vehicles, JCBs, dumpers, etc. Also, there is a lot of manual activity going on – welding, hammering, shouting, etc. Together these activities at a construction site constitute noise pollution. The noise level around a busy construction site could easily reach up to the level of 95 dB.
3) Organized Events
Many social events are organized in an urban settlement from time to time. Marriages, birthday celebrations, annual functions in schools and colleges, religious events are some of the regular events in an urban settlement. Such events commonly use loudspeakers and high sound music systems, which potentially contribute to noise pollution. In the events with huge public gathering, cheering and whistling, as in cricket match, the noise levels could easily reach up to the level of 105 dB.
How to Control Noise Pollution
Noise pollution could be effectively controlled by the following measures:
1) Noise Suppression at Source
The suppression of noise at source could be achieved by making some constructional changes or by using less noisy machineries and equipments. Regular servicing of transport vehicles and construction machineries will help reduce noise pollution at the source.
2) Noise Control at the Receiver’s End
People, who are working in or near a noisy construction site, must use earplugs, helmets and similar equipments to reduce the effects of noise. Also, the houses constructed in the vicinity of noisy areas must be constructed using the material that absorbs noise. The doors and windows must be able to absorb noise and vibration and also completely isolate the room from the outside environment.
Till now noise pollution and its effects have been grossly neglected. But now governments around the world are starting to realize the severe health and environmental hazards caused by noise pollution. Noise pollution when it reaches beyond a specified limit could cause hearing loss and serious mental disturbances. There is a need to take collective measures for minimizing the effects of noise pollution. Persons at the source as well as the receiver’s end must take responsibility and take necessary measures to reduce the generation and reception of noise respectively.
