Around the world, there are six major types of pollution such as water pollution, air pollution, solid waste, radioactive and nuclear energy, and lastly noise pollution. Noise pollution, or environmental noise, is displeasing sound created by humans, animals, or machines, that disrupts the activity or balance of domestic and animal life. The most common source of the pollution is brought on worldwide by transportation systems that include motor vehicle noise, aircraft noise and rail noise. Other sources that cause the pollution, both indoor and outdoor, are: car alarms, emergency service sirens, office equipment factory, barking dogs, appliances, fireworks, compressed air horns, construction work, grounds keeping equipment, audio entertainment systems, and even noisy people. Like the other forms of energy pollution, such as heat and light pollution, noise pollution contaminants are not physical, but instead are waves that interfere with natural-occurring waves of a similar stature. Sounds that are not natural, or cause a disturbance of any natural process or causes human harm, even if it does not occur on a regular basis, the noise is to be considered noise pollution. Although most of the noise pollution is caused in urban areas like big cities, rural areas are not immune to noise pollution. Train and airplane noise can disrupt the wildlife habits, therefore, affecting the natural manner in which the animals, in areas around train tracks and airports, hunt, mate and live. Noise pollution harms humans and animals by causing hearing loss, hearing problems, heart disease (as a result of stress), sleep disruption, and in severe cases even mental instability. Noise pollution, although rarely spoke of, causes, and will continue to cause...

...e in blood pressure, a change in heart rate, a rise in blood cholesterol, or an excessive secretion of hormones. These stress reactions can cause actual damage to the circulatory, cardiovascular, and gastrointestinal systems or, any other vulnerable bodily system. Even though the direct physical consequence of listening to loud sounds, especially over a period of time, can be hearing loss, sounds or, rather noises at lower volumes can have an indirect impact on our physiological and psychological systems. It is not only the ear that can be hurt by noise but to our over all health. No person can concentrate on a work project of there is constant drilling at a nearby construction site. It is impossible to enjoy a television program when overhead jets constantly drown out the sound. It is hard to fall asleep if your upstairs neighbor’s stereo system is blasting away.
The unit used to measure the intensity of sound is called the decibel(dB). Sounds that measure up to 75dB are considered to be in the "safe zone". Constant exposure to to sound at these levels are very unlikely to cause any lasting damage to long term hearing. The sound of regular volume conversation measures at around 60dB and the sound of a running dishwasher measures at roughly 75dB. Sounds around the 85dB level are considered a moderate risk to hearing. Exposure at these levels for extened periods of time may lead to some form of damage causing NIHL. Sounds at these levels include heavy traffic and crowded areas at 85dB, active subway stations at 95dB and listening to an mp3 player with ear buds at maximum volume at 105dB in which listening for just 15 minutes can cause permanent damage. Sound at 120dB and above are in the "danger zone". This level of sound is to be avoided at all cost as exposure even for a short pulse will lead to immediate permanent damage. This level includes the sound of ambulance sirens at 120dB, a jet taking off at 140dB and gunshots at 165 dB and above. (Rabinowitz,
Music has been suggested to affect the body’s physiological patterns in many ways. A study done in 2003 (Yamamoto et. al) exemplified the wavering levels of neurotransmitters as the type of music was changed. When the participants listen to slow-rhythm music their plasma levels of norepinephrine decreased, and when they listened to fast-rhythm music their plasma levels of epinephrine increased. Norepinephrine is a hormone generally known for mechanisms of the sympathetic nervous system, originating the fight or flight response. When it is lowered, the body’s stress level is suppressed, caused by a decrease in blood pressure. Epinephrine is a similar hormone, commonly referred to as adrenaline, which has been known to produce sudden responses to combat stress. An increase in plasma levels would increase the heart rate and dilate air passages to promote the expansion of oxygen to the body’s vital organs. By simply choosing a different pace of music, the way our physiology works can be completely altered.
The purpose of this paper is to define stress and how it effects the body's physiological systems. This paper will include the normal functions and organs involved in the following five physiological systems, cardiovascular, gastrointestinal, respiratory, immune and musculoskeletal. This paper will also include a description of a chronic illness associated with each physiological system and how the illness is affected by stress.
The noise of Aircrafts was historically a major environmental issue for the airline. It is still high on the agenda of public concern. Noise disturbance has a variety of difficult issues to assess because it is open for self- reactions. Its impact is not one permanently on the actual environment, but it can have many effects on the people living in the area of the airport, including: interference in c...

Have you ever considered that several of the noises you hear are noise pollution? The thought of pollution, to the majority of people, brings reflections of chemical spills, radiation, and holes in the ozone layer, and noise is usually last on the list. "The term "noise pollution" is the term used to describe environmental pollution that deals with annoying or harmful noises and is constantly happening"(1). Some common examples of noise pollution, that many people take for granite, are lawn mowers, airplanes, and car alarms. Noise pollution should be taken seriously because it can cause permanent hearing loss.
One of the major problems that society faces today is noise pollution. Everywhere people go there is always something that is making a sound. It can be very loud such as a plane flying overhead, or it could be quiet like the fan of a computer. When a person is exposed to certain noises for extended periods of time it can not only damage their hearing, but also effect their mood, energy level, and productivity. As a result, there has been a push in the last fifty years or so to silence some of the annoying sounds that assault people’s ears everyday. While it might seem as simple as covering ones ears, the scientific community has been applying their knowledge in the hope of creating a more peaceful world.
Until 10 years ago, air pollution was thought to be just an urban or local problem until it was discovered that the pollutants could move across continents and oceans. Air pollution is the fundamental factor that causes greenhouse gases, hence climate change and global warming. Air pollutants are the waste products generated from industrial and other processes. They usually come in gases, though aerosols (particles suspended in air, emitted as or formed by transformatio...
Air pollution is caused by many things such as car fumes, burning of fossil fuels,
Pollution is causing the destruction of environments and habits resulting in many adverse affects. The types of environments that are heavily damaged by pollution is normally freshwater ones. Polluting factors such as untreated sewage, mining waste, acid rain, fertilizers and pesticides
bother most people, and they think that it will not harm them. People burn down
Effects on wildlife Animals face effects of air pollution, when toxic chemicals are released in the atmosphere thus causes animals to migrate. Eutrophication also goes as an example of its effect on the environment. Solutions to air pollution Conserve energy A large amount of fossil fuels are being burnt for electricity. To reduce air pollution, we should burn less fuel and avoid wasting electricity. We can also conserve energy by turning off the lights and appliances when we are not using them.
Stress on individuals can bring numerous numbers of health problems, for example; heart disease. Researches have declared that having stress increase heart rate and blood flow, and causes release of cholesterol and triglycerides into the bloodstream. Another example is the Alzheimer’s disease, stress could potentially worsen Alzheimer’s disease causing its brain lesions to form more quickly. Individuals should be aware that being stressed could lead to major problems in the long run, but with the proper care and staying positive could help prevent further damages.
Efforts to improve the standard of living for humans--through the control of nature and the development of new products--have also resulted in the pollution, or contamination, of the environment. Much of the world's air, water, and land is now partially poisoned by chemical wastes. Some places have become uninhabitable. This pollution exposes people all around the globe to new risks from disease. Many species of plants and animals have become endangered or are now extinct. As a result of these developments, governments have passed laws to limit or reverse the threat of environmental pollution.
Pollution is a massive problem that the earth faces. Pollution is the action or process of making land, water, air, etc…, dirty and not safe or suitable to use. Pollution of air, water, and soil are the most complex issues. Various types of gases and toxins that are released by industries
