Noise Pollution

You are!

Yes.

Ringing ears is a sign of an infection or that you have too much wax in your ear.The way to get rid of it is to go to a doctor and get drops or have them syringed

You can not make natural gas.....it is NATURAL.

It is because the United states didn't have the money to make power lines for the electrically driven cars.

Noise at hazardous levels are so over the entire human audiological spectrum, but long-term exposure reduces the response from the highest frequency (18-20 kHz) downwards.

ther it is the roar of a jet plane overhead or the sound of a barking dog a block away. The actual loudness of a sound is only one component of the effect it has on human beings. Other factors to consider are the time and place, the duration, the source of the sound, and whether the listener has any control over it. Most people would not be bothered by the sound of a 21-gun salute on a special occasion. On the other hand, the thump-thump of a neighbour's music at 2 a.m., even if barely audible, could be a major source of stress. Measuring Sound by Decibel (dB) The decibel (dB) is a measure of sound intensity; that is, the magnitude of the fluctuations in air pressure caused by sound waves. The decibel scale is logarithmic, not arithmetic. This means that a doubling of sound intensity is not represented as a doubling of the decibel level. In fact, an increase of just 3 dB means twice as much sound, and an increase of 10 dB means ten times as much sound. A sound pressure level of 0 dB represents the threshold of hearing in the most sensitive frequency range of a young, healthy ear, while the thresholds of tickling or painful sensations in the ear occur at about 120 to 130 dB. Decibels are usually measured with a filter that emphasizes sounds in certain frequencies. The "A" filter (dBA) is the one most frequently used. The "C" filter (dBC) puts more weight on low-frequency sounds such as the bass in amplified music. The perception of loudness by the human ear is not directly proportional to the decibel level. For example, a sound 10 dB greater than another is not perceived as being ten times as loud but only about three times as loud. The intensity of noise diminishes with distance. Outdoors, and in absence of any close reflecting surface, the effective decibel level diminishes at a rate of 6 dB for each factor of two increase in distance. For example, a sound measuring 100 dB at 10 metres would be 94 dB at 20 metres, 88 dB at 40 metres, and so on. How loud does noise have to be before it's dangerous? Because permanent hearing loss is usually a long-term process, it is impossible to know at exactly what point noise becomes loud enough to cause damage to the ears. The U.S. Environmental Protection Agency has established 70 dBA as a safe average for a 24-hour day. (This figure is based only on the risk to hearing, and does not take into account other health factors such as loss of sleep.) Since sound intensity doubles with every increase of 3 dB, the time of safe exposure would be cut in half with each such increase. Thus a worker should wear ear protection if exposed to a steady 75 dBA for eight hours, 78 dBA for four hours, and so on. Brief exposure to noises of up to 100 dBA is not considered risky, provided the average remains within the prescribed levels. Actual limits for labour tend to be more permissive. In most jurisdictions, workers are permitted to be exposed to up to 85 or even 90 dBA for eight hours. Using the higher of these figures, the sound level in a typical nightclub, 110 dBA, could pose a risk of permanent hearing damage after as little as four minutes of exposure. Of course, noise is dangerous in other ways too. It can be a cause of stress, illness, suicide, aggression, and violence. As stated above, the volume of noise is only one component of its effect.

In Canada and the United States there are no national, provincial, or state laws that give blanket protection against noise, though there are some specific regulations governing manufacturing standards, air traffic, vehicle mufflers, and so on. Criminal laws may also cover things like noisy parties. Governments have traditionally viewed noise as a nuisance rather than an environmental problem. As a result, most regulation has been left up to municipal authorities. Noise bylaws and ordinances vary widely from one municipality to another and do not even exist in some towns and cities. Where they exist, they may contain a general prohibition against making noise that is a nuisance to other people, or they may set out specific guidelines for the level of noise allowable at certain times of the day and for certain activities. Exceptions are generally made for activities considered legitimate or necessary, such as lawn mowing or garbage collection. Regardless of how lax or stringent a local law may be, enforcement is difficult. Many municipalities do not have adequate resources to follow-up on complaints. Even where a municipality has an enforcement office, it may be unwilling to do more than issue warnings, since taking offenders to court is expensive. The police may also act on certain kinds of noise complaints, but generally do not assign them a high priority. For persistent nuisances, the individual may have to seek damages through the civil courts. This can be a long, costly procedure with no certainty of success. In short, legal protection against noise is very patchy and often inadequate. Is there evidence that noise can make us sick? Yes, though much of it is buried in scholarly journals. We know of only one book in print: Noise & Health, edited by Thomas H. Fay, published by The New York Academy of Medicine (1991). This book presents a critical and comprehensive review of available world literature on the effects of noise on all of the body's systems. It defines noise and its sources, documents the specific health hazards of noise on the body, and indicates needs for further research.

As for exact DB's I'm unsure, but mine is about the same as a well tuned lawn mower.

It in a way can be pin-pointed because every single chemical in the world is slightly different with a different can/bottle, and could in fact be traced.

Most places where trawling is still an issue the only way to prevent trawling is taking extensive research of species change in the oceans due to trawling and presenting the reasearch to the local government. This will take a long time however if legislation is put in place to stop trawling there can be great benefits to the environement.

Schemes like this are ongoing in countries like Cambodia where the compant is working with the government to prevent trawling and protect seahorse and nudibranch.

Some things to help to minimize noise pollution are... *Get a muffler for outdoor equipment (lawn mower, leaf blower, car, chainsaw, ect.) *Rake leaves by hand, don't use a noisy leaf blower. *Trim bushes or shrubs by hand, don't use a noisy bush trimmer. *Sound proof rooms that might have music conducted in them, like a room with a piano or if someone in the hosue plays drums or guitar or whatever. This can be done simply with curtains, window inserts, carpeting, and closing windows and doors. *Don't blast music on the radio or computer or speakers. Be considerate of your own ears and those of other around you. *Don't slam doors / car doors, close them eaily and with only as much force as needed. (People don't usually think of this, but imagine - how loud is it when you slam your car door? Pretty tolerable. But imagine thousands of people doing so. Now that can start to get loud. *Turn off the TV or radio when you aren't actually fully listening to it. *Train your dog not to bark so much. *Don't yell. Have civil conversations. Call someone or go find them instead of yelling across the street for them, for example. *Plant trees and bushes around you house. They help keep the air clean, absorb sound, give privacy, and add nice design and looks to a house. *Do noisy things (dishes, hammering, ect.) over or on a rubber mat to reduce noise. *Put carpets, rugs, mats, throw rugs, ect. in your house / mats outside. *Put fabric window coverings instead of plastic or wooden shades / blinds. *Don't rev up a motorcycle or car unless it is actually needed for the drive. *Don't beep your carn horn "just because", make sure it is a legit cause.

The most affected areas are cities because they have a lot of transportation noises. Poor city-planningmay give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area.

: 1. Noise pollution causes our ear drums a hugh problem and mostly make us dum. Mostly it causes us irritation and not allow us to concentrate on our work. : 2. Noise pollution can be stopped by planting more trees as the plants absorp more sound,avoid election campaign,mostly we can avoid loudspeakers boom. : Suggestion: : 1. Many of the people make their Television sound high and disturb the surrounding household. : 2. During the time of election people can start practising of sticking only the posters instead of using loudspeakers to announce their imformation. So, current and the noise pollution can be avoided.

Nocturnal asthma is a term used to describe the asthma of patients whose symptoms strike mostly at night - often while the patient is sleeping. The majority of these attacks occur between midnight and 8 a.m., peaking on average around 4 a.m. This is when pulmonary (lung) functions are at their lowest level, because circulating blood levels of epinephrine and cortisol - which protect the body against asthma - are at their lowest levels. Nearly 75 percent of asthma patients experience increased symptoms at night, according to the American Academy of Allergy, Asthma and Immunology. Frequent bouts of nocturnal asthma may indicate that a patient's asthma is not being properly controlled. Experts believe several factors may be responsible for the increased incidence of asthma symptoms at night. These include the body's circadian rhythms, the internal clock that regulates the ebb and flow of various chemicals and body functions. Patients with nocturnal asthma should consult a physician. This condition is often an indicator of severe asthma or asthma that requires further treatment. Certain behavioral modifications can reduce the likelihood of night-time symptoms. Medications also are available in time-release or long-lasting formulations to ensure that a patient with nocturnal asthma gets the medicine they need when they need it most.

False; noise pollution form a race track is not an example of positive externality. It is more likely an example of negative externality.

different parts inside the gearbox will have driped dry and make more noise after starting from cold this noise should go away fairly quickly as the running gears move the oil around the gear box

Ø Noise pollution is one of the most neglected forms of pollution despite causing huge environmental damage, especially in oceans. For instance, U.S. still doesn't have some federal body that would regulate noise pollution.

Ø From birds in the sky to elephants on land to dolphins in the sea, noise pollution is threatening all types of species and altering the way in which these animals communicate, mate and even protect themselves from larger predators.

Ø Unwanted noise causes species to communicate louder which is known as Lombard effect.

Ø There are about more than 500 million cars on the planet and by 2030 it is expected to double to 1 billion cars. More cars will mean even higher levels of air and noise pollution.

Ø Noise Pollution is a contamination of the quality of the sound in the air (Example loud honking, construction sites)

To write a report on pollution of air and water, you should discuss the harmful impact of pollution. Discuss what causes pollution, and also how to help reduce pollution.

No. Police can pull you over for noise pollution so they tend not to make them do higher.

noise pollution is a very nasty noise which can damage your ears. people become deaf because of noise pollution! how to stop noise pollution, well, everyone has to play their part really. when your down the street don't shout or scream, building men could possibly work a little quieter, cars could reduce on speeding (actually, the less cars on the road, the better!) these are the sort of things which can stop noise pollution. trust me, it's a horrible thing! my great friend became death because of noise pollution!

please, if you have a comment on my answer please comment!
