What Is Noise Pollution?
Definition
Noise pollution is generally defined as regular exposure to elevated sound level that may lead to adverse effects in humans or other living organisms. According to the World Health Organizations sound levels less than are not damaging to living organism regardless of how long or consistent the exposure is Exposure for more than 8 hours to constant noise beyond 85 dB may be hazardou. If you work for 8 hour daily in close proximity to a busy road or highway you are very likely exposed to traffic noise pollution around 85dB.
noise pollution noise pollution is the propagation of noise or sound with ranging impacts on the activity of human or Pollution is one of the main concerns, the world is dealing with amidst all the problems and issues. However most of the time it is air pollution and water pollutions that is spoken about. The limelight may not be on Noise Pollution but it also has tremendou negative effect. Noise is a word that has been coin from the Latin term Nausea. Nausea is a health issue that causes a sensation of vomiting and dizziness. Coin cidently high pitch noise can results in sickness and even permanent loss of hearing. So we must take measures for noise pollution prevention The word noise is derived from the Latin word ‘Nausea’, which means sickne in which one feels the need to vomit. Noise is the unpleasant and undesirable sound which lead to discomfort in human beings. The intensity of sound is measured in decibel(dB). The faintest sound that the humans ear can hear is Db. Due to increasing noise around the civilization noise pollution has become a matter of concern. Some of it major causes are vehicle aircraft industrial machines, loudspeakers, crackers, etc. When used at high volume, some other appliances also contribute to noise pollution, like television, transistor, etc.
Types of Noise Pollution
Man-Made Noise Pollution –
These include a wide range of noise disruption that occurs as a result of man-made noise likes, vehicles, honking, Air traffic, construction, fights, loud music, and various other household noise.
Environmental Noise Pollution – These are noise emitted as a results of environmental issues like Earthquakes, thunderstorm, Volcanic eruptions, howling of animals.
Noise Pollution Examples
Following are the examples of noise pollution.
- Unnecessary usage of horn.
- Using loudspeaker either for religious functions or for political purposes.
- Unnecessary usage of firework.
- Industrial noise
- Construction noise
- Noise from transportation such as railway and aircrafts.
Reducing noise from appliances:
Items, such as air conditioning units, heaters, fans, and other appliance can contribute to over all noise levels in the home. Try turning them off more often or setting a time so they only switch on at certain time.
Reducing noise from media devices:
Consider the volume and duration of noise from music, televisions, radio and video games. Avoid having unnecessary noise playing in the background for long periods or listening to sounds at to high a volume. It may be useful to set a side dedicated time for watching TV or listening to musics.
Repair or replace old machinery:
Old appliances, vehicle, and other item can be louder than newer models. Consider upgrading or replacing noisy household items.
Soundproofing:
Adding insulation strategically around the home can help muffle sound from other rooms, neighbor , outside. Rugs, carpet, and curtains may also help.
Create more quiet time:
Try to regularly set aside time for quiet activities, as reading, puzzled, or creative hobbies. Avoid playing music or having background noise during this times.

Noise pollution
Noise pollution is any unwanted unnecessary and stressful noise that affected the physical, mental and social activities of human beings as well as animal life in a harmful way. Noise pollution is inevitable in area's prevailing the human population since several of the human processed or activities like factory/industry machinery transportation system, construction, spiritual activities and community activity (e.g television, music systems, machinery, nightlife, social activities, domestic appliance etc.) generate some sort of noise [16]. Noise is found all most every where. Physically sound and noise are often used as synonym. Technically noise is regarded as any undesired sound and disturbance within a useful frequency band. A sound is a form of energy produced by vibrating bodied which upon reaching human ears, produces a form of hearing sensation. All vibrating bodies do not produced sound in the audible range from 20000 Hz. The intensity of sound is measured in decibel. All the sounds produced outside this range are undesired for normal humans hearing. This noise is known as the “unwanted sound” and is distinguished by the requirements or tendency of the person receiving it. There are mainly three classification of noise pollution .
Atmospheric noise: It is also known as static noise which is the noise occurring due to the natural processes taking place in the atmosphere like lightning discharged in thunderstorms or other natural electric disturbances. Most of the atmospheric noise is generates in the very low frequency and low frequency range of the radio spectrum. Thus atmospheric noise becomes less severe at the high frequency and very high frequency, where man-made noise dominates mainly in urban area.
Environmental noise: It is the accumulations of noise pollution occurring outside the environment and neighbouring. Many factor maycto this type of noise, for example, transportation that uses a motor to make a loud noise (like trains, trucks, cars, helicopter, watercraft, spacecraft and aircraft) and various amusing activities like sport and music performances. The environmental noise depicts the live lines of human beings and is thus included in most of the daily activitie of human life. The random noise of people talking, various alarm, announcements and bioacoustics noise from animals or birds all produce environmental noise.
Occupational noise: It is also called industry's noise and is defined as the noise received by workers during their jobs. It may be caused by the work environment or the use of machinery and also varies in characteristic like loudness and frequency components.
In urban areamore than half of the total environmental noise pollution is the produced solely by traffic noise [18,19]. The traffic noise included motor noise as well as horn-honking noise. In the last few decades, this extensive increase in traffic noise pollution has occurred because of increased vehicles, low turnover of old vehicles, an underdeveloped road network and increased urbanization. Also, the unnecessary usage of horns and loudspeakers, either for spiritual or political purposes, and the unnecessary usage of firecrackers all these constitute noise pollution and harm human health and social activities.
Measures to Control Noise Pollution Around You
Noise pollution created due to factor outside one’s home is unavoidable, but an individual can easily control the factors inside their home. One can reduce noise pollution through the followings ways:
1. Turning Off Appliances
Appliances such as air conditioners, television, heater and fans contribute to the overa noise level at home and offices. One can easily turn these electronic devices off when not in user. This way an individual can easily avoided un wanted noise at home.
2. Reducing the Volume of Media Gadgets
The use of media gadgets like television, computer, mobiles and iPad have become common. Howeve one can lower the volume of these device's while using them and completely switch them off when not in use. It can benefits individuals if they dedicate separate time for watching television or playing games on the computer. This way they can have an hour's without any noise.
3. Replacing/Repairing Old Machines
Old machinery like the washing machine or mixer grinder trends to create a lot of noise compared to the new ones. If repairing the old machine can stop the noise emission then it’s a win-win situation for the user. However if repairing the machine cannot salvage its noise one should consider replacing them with new ones.
4. Soundproofing the Rooms
Soundproofing all the rooms in the house is the best way to cancel out all the sound coming from outside the house. For instance a party is going on in the neighbour house, and they are playing music on the loudspeaker, the sound proof rooms will cancel out the noise.
5. Using Ear Protection
Ear protection like earplugs and earmuff can come handy when one is outside the house. An individual can control the noise creating factor at home, but one cannot do much about noisy outside elements. This is where earplugs come in handy, as they will reduced the impact of the sounds. For example, construction is going on a building beside an individual office, but he can do nothing about it. Instead, he can use earplug to protect himself from hearing damage.
Sound is an essential element in human life but it becomes noise when this sound exceeds recommended decibels. These un sounds together create noise pollution and interfere with the live of humans and animals.Noise pollution negatively impact humans by affecting mental and physical health. In addition the disease caused by noise pollution can be highly detrimental to human health.
