Depending upon their existence in nature pollutants are of two types, namely: i Quantitative and ii Qualitative pollutants. It has become an increasing sources of annoyance to the large number of people who live in the vicinity of air ports. Among all the environmental noise pollutants, within an urban setting, the traffic noise is the most common. Noise is an unwanted and unpleasant sound. Our complete results for the Puja pandal in Sector-5 are given in Table 1.
This is usually caused by very high intensity impulse type noise, that can result from an explosion, or sudden excessive noise of about 150 dB or more. It can impair the ability to enjoy one's property and leisure time and increases the frequency of antisocial behaviour. Assessing canine hearing loss Electricity How does cold affect hearing aid battery life?. This study measured ambient noise levels in four halls of residence in the University of Cape Coast, Ghana to ascertain compliance with permissible limits and determine the peak period of the noise generated. Man is the part of environment and he cannot be isolated. School projects on pollution that involve several steps are appropriate for this age group. Most urban communities have rules to prevent noise pollution from getting out of control.
Situate your home so that your bed isn't right next to your noisy furnace or air conditioning unit. In fact, some of the major world religious e. Since the standards will be source related, they will require for the most polluting industrial processes, particularly those using toxic substances, application of the best available technological solutions, and also be an instrument for technological up-gradation. Since loudspeakers are used in all such programmes, the inÂhabitants of houses in the neighbourhood of pandals are exposed to unÂdesirable levels of noise at night and this interferes with their sleep and relaxation. It would keep you from sleeping; as a result, it would harm your health.
Use of loudspeakers and amplifiers should be restricted at a fixed intensity and hours of the day. Under this project, Tiwari et al recently investigated the possibility of acid rain in Rourkela. The last three lines at the bottom of Table 4 give the overall minimum, maximum and average noise levels for these three categories of locations. Diesel engine trucks are generally 10 dB nosier than petrol engine trucks and 12 to 18 dB nosier than cars. Examples â Traffic or Aeroplane engines. Even physiological or psychological disorders may be caused by excesÂsive noise. The objective is to integrate environmental considerations into decision making at all levels.
Besides affective health noise is also a significant factor in economic losses. An interesting case is the slum area of Sector-2 see Table 2. This project report will help you to learn about: 1. The most commonly used scientific acoustic unit is the decibel dB. Internal combustion engines should be properly silenced. Wheeling buses and racing cars and trucks are yet another source of noise produced due to the friction of tyres on road.
If we confront these tolerance limits with the levels of traffic noise in Rourkela, we find that at most of the 28 locations, basic noise levels minimum values and frequent peaks average values are within day-time tolerance limits. Pollution has been changed the atmospheric conditions. Abatement of Noise Pollution: In general, ears have some protective reflexes which have only limited effect against loud noise. This Table shows the tolerance limits for both day and night. The noise levels were measured during peak hours of activity. Article shared by : A project report on environmental pollution. The main sources of noise during religious festivals are the loudspeakers, which are freely used on such occasions.
Compare the noise level generated by commercial airplanes during take-off and landing. It adversely affects future generations by degrading residential, social, and learning environments with corresponding economic losses. Increasing traffic has given rise to traffic jams in congested areas where the repeated hooting of horns by impatient drivers pierce the ears of all road users. But if a firework explodes too close to you, it could damage your ears. Miscellaneous Sources: The automobile repair shops, construction â works, blasting, bulldozing, stone crushing etc. Standards will not merely be a regulatory tool but will be mechanism to promote technological up-gradation to prevent pollution, conserve resource and regulate waste. To get accurate results, measurements were made by following exactly the procedure recommended by the manufacturer in the Operation Manual, and taking all the necessary precautions.
The environment has been classified into: i Physical or abiotic environment: It is composed of external physical factors like temperature, humidity, water, minerals and gases etc. Various types of devices for noise making have been used for this purpose. Effects of Noise Pollution : i Hearing Damage from Noise Exposure: There is no doubt that noise pollution can damage the ear and cause temporary or permanent noise-induced hearing loss, depending upon the intensity and duration of the sound level. Discussion: We notice from Table 1 that Rourkela has a fairly large number of motor vehicles and roughly 83% of these are scooters and motorcycles, which produce more noise on the road than cars. Thus Rourkela offers a unique opportunity for the study of environmental problems.
Facts About Noise Pollution You've Probably Never Heard Of
The combined area of Steel Township and Civil Township of Rourkela is 121. Due to greediness he has exploited their environment, which gave birth to several environment implication on the name of progress he has cut the forest, our lakes has been poisoned with hazard chemical. Heavy trucks, buses, trains, jet-planes, motorcycles, scooters, mopeds, jeeps the list of vehicles is endless but the outcome is same-noise pollution. Rourkela is the most important industrial city in the state of Orissa. Firms dilute waste to lower pollutant concentration for discharge into a sewage treatment plant or directly into air or water, or to inject them more easily into deep wells. Any effort to disturb this process is termed as Environment pollution. Most people are familiar with air and water pollution.
For an even easier solution, try hanging blankets on the walls or installing extra bookcases filled with books. Noise pollution can be effectively controlled by taking the following measures: i. We find from Table 1 that the noise levels in localities having multi-storey houses are almost always higher than those in the localities having single-storey houses. No matter where you are, whether it's on a noisy subway car or in your own kitchen, you can try this technique to calm yourself down. Civil Township or old Rourkela, on the other hand, is just like any other unplanned city. Research the effectiveness of rubberized asphalt as a traffic noise mitigation measure.
