Global changeis one consequence… Although environmental pollution can be caused by natural events such as forest fires and active volcanoesuse of the word pollution generally implies that the contaminants have an anthropogenic source—that is, a source created by human activities. Pollution has accompanied humankind ever since groups of people first congregated and remained for a long time in any one place.
Council on Environmental Quality, Results and Discussion Hearing loss can be entrapping in onset. Years of traumatic exposure to high levels can occur before symptoms become manifest. The popularity for portable sound equipment such Noise pollution on students Walkman-type radios and tape players has already has already produced a sharp increase in clinically verified hearing loss, especially among rock music addicts who prefer their music very loud Benarde, Obviously, the Walkman-radio industry believes it is not their products that are the problem; rather it is improper use.
If, they say, the volume is kept down, there would be no problem, which is equivalent to saying that if we all drove cautiously there would be no accidents. Considering that earphone listening has been around for some 20 years, why has the problem only recently surfaced?
Apparently the pattern of listening has changed. Currently, earphones are used while walking or running on noisy easy streets rather than in the privacy of the home or other relatively quiet area where the listener did not wish to disturb others.
Now the volume must be turned up to overcome the noise of city traffic. The listener wants the Walkman to blot out the "noises of the city. A similar result occurs to users in noisy factory or industrial environments.
Since to these people, louder is better, the makings for an epidemic of hearing loss are at hand. The Occupational Safety and Health Agency OSHA has set the danger level at 95 decibels dB and above for 4 or more hours per day as likely to induce permanent hearing impairment Benarde, According to initial reports by officials of the Naval Ministry, underwater sound-detecting gear functioned poorly making it difficult to pinpoint the location of the subs.
It was later determined that the problem lay elsewhere. The young Swedish sailors manning the monitors had in fact developed hearing losses as a consequence of excessive exposure to rock music.
On learning this, other governments moved quickly to ascertain the hearing acuity of detectors. Consequently, the problem of exposure to sound levels detrimental to hearing takes on new and more serious dimensions Benarde, Yet it has been argued that because noise produces no dramatic ill effects, the public has been largely uninterested in its suppression.
It may be more to the point to say that the degree of annoyance and discomfort that people will endure is astonishing. Although noise is an integral part of civilization, it would appear that unless some definite steps are taken to reduce the present inordinate levels in both industry and community generally, more people will become auditory cripples.
A measure of this is seen in the number of communities moving forcefully to reduce noise levels in their home areas.
Vexation and anger with increasing noisy communities is not a uniquely American problem. Navy fighter aircraft, F-4, A-6, and E-2 jets, of them on station aboard the aircraft carrier U. Midway, fly over Yamato as they come in for landings at nearby Atsugi Air Base.
As the jets sweep low they rattle houses and residents. The evenings are the worst with more takeoffs and landings at full power and thus maximum noise, at a time, of curse when the people are trying to sleep Benarde, Be that as it may, the residents are unimpressed, cannot sleep, and prefer the training sessions to be moved elsewhere.
No one wants them and there wretched noise. Airplane noise can be a much greater disturbance to sleep than other noises. Aircraft noise began to be a major problem with the great surge in air transportation that followed World War II.
Since then, annoyance to people living near airports caused by the noise of jet takeoffs and landings has become a psychophysiological and economic problem of enormous magnitude and complexity. Still a third escalation in aircraft noise will occur when supersonic transports come into commercial operation, and if general aviation and, above all, vertical take off and landing.
At the same time, under the pressure of population, communities tend to expand toward airports and thus to enter into zones of higher noise. Also, an increasing number of people are working in airports and in other areas of the aviation industry.
In the United States airport noise has been hit the hardest, than any other developed country due to the large geographic area.Air Pollution Control Engineering (Handbook of Environmental Engineering) (v.

[email Noise pollution takes place when noise and unpleasant sounds cause temporary disruption in the. Our role. Environment Protection Authority Victoria (EPA) plays a role in protecting the community from noise pollution.
It develops policies, regulations and guidelines to prevent and control noise, and partners with other agencies (including local councils, Victoria Police and transport agencies such as VicRoads) to provide advice on the .
Noise pollution (or environmental noise) is displeasing human-, animal- or machine-created sound that disrupts the activity or balance of human or animal life. A common form of noise pollution is from transportation, principally motor vehicles.
