Noise Pollution Essay
Noise reduction can be done by using rigid sealed enclosures around machinery lined with acoustic absorbing material. Isolating machines and their enclosures from the floor using special spring mounts or absorbent mounts and pads and using flexible couplings for interior pipelines also contribute to reducing noise pollution at the source. Regular and thorough maintenance of operating machinery. We should reduce mechanical run out of shafts.
By reducing this source of vibration excitation many components like bearing gears and cans may generate less noise and have generate life. We must improve lubrications. We should install bearings correctly. Improper installation sometimes is the reason for bearing noise problems. Traffic volume and speed also have significant effects on the overall sound. Example: doubling the speed increases the sound levels by about 9 dB and doubling the traffic volume number of vehicles per hour increases sound levels by about 3 dB. A smooth flow of traffic causes less noise than a stop-and-go traffic pattern.
Thus proper highway planning and design are essential for controlling traffic noise. Establishing lower speed limits for highways that pass through residential areas, limiting traffic volume and providing alternative routes for truck traffic are effective noise control measures. Using efficient flow techniques: for reducing noise associated with high fluid velocities and turbulence.
Reducing fluid jet velocities: As jet noise is proportional to the eight power of jet velocity. Highly absorptive interior finish material for walls, ceilings and floors can decrease indoor noise levels significantly. Increasing distance from the noise source and the recipient offers a passive means of control:.

Municipal land- use ordinances pertaining to the location of airports make use of the attenuating effect of distance on sound levels. Use of earplugs and earmuffs. Specially designed earmuffs can reduce the sound level reaching the eardrum by as much as 40 dB. Besides these in general making Legislation, Educating and bringing awareness in the people is common for control of any pollution Example: Ban on loud speakers from 10 pm to 6 pm.

Industrial activity, waste disposal, agricultural activities, acid rain, and accidental oil spill are the main causes of soil pollution. This type of contamination influence health of humans, affects the growth of plants, decreases soil fertility, and changes the soil structure. Water pollution is able to lead our world on a path of destruction. Water is one of the greatest natural resources of the whole humanity. Nothing will be able to live without water. However, we do not appreciate this gift of nature and pollute it without thinking.
The key causes of the water pollution are: industrial waste, mining activities, sewage and waste water, accidental oil leakage, marine dumping, chemical pesticides and fertilizers, burning of fossil fuels, animal waste, urban development, global warming, radioactive waste, and leakage from sewer lines.
There is less water available for drinking, cooking, irrigating crops, and washing. Light pollution occurs because of the prominent excess illumination in some areas. They have deadly effects on many creatures including mammals, plants, amphibians, insects, and birds.

Every year many bird species die colliding with needlessly illuminated buildings. Moreover, artificial lights can lead baby sea turtles to their demise. Noise pollution takes place when noise and unpleasant sounds cause temporary disruption in the natural balance. It is usually caused by industrialization, social events, poor urban planning, household chores, transportation, and construction activities. Noise pollution leads to hearing problems, health issues, cardiovascular issues, sleeping disorders, and trouble communicating. Moreover, it affects wildlife a lot. Some animals may suffer from hearing loss while others become inefficient at hunting.
It is very important to understand noise pollution in order to lower its impact on the environment. Radioactive pollution is the presence of radioactive substances in the environment. It is highly dangerous when it occurs. Radioactive contamination can be caused by breaches at nuclear power plants or improper transport of radioactive chemicals. Radioactive material should be handled with great care as radiation destroys cells in living organisms that can result in illness or even death. Environmental pollution has negatively affected the life of both animals and human-beings.
The only way to control current environmental issues is to implement conservation methods and create sustainable development strategies. We should find some effective solutions in order to restore our ecological balance.
First of all, we should make sustainable transportation choices. We should take advantage of public transportation, walk or ride bikes whenever possible, consolidate our trips, and consider purchasing an electric car. It is very important to make sustainable food choices. Choose local food whenever possible; buy organically grown vegetables and fruits or grow your own.
