摘抄的经典，慢慢甄选Noise PollutionWe know the sounds of cities are loud enough to cause great harm to people's hearing .S. One person out of twenty has got some hearing loss. And all over the world the situation is getting worse and worse all the time since the noise increases with the population.With the development of machines, noise has also increased greatly in the 20th century. We live surrounded by loud planes, trucks and electric tools. TV sets and radios add up to 90 or J00 decibels, a certain unit used to measure the loudness of sound. A normal dialogue reaches 55 decibels; a plane goes to 100, and an ordinary train, reaching the station, can be twice as loud as the loudest plane. Disco music reaches about 118. At decibels the ear stops hearing sound, and pain starts. How terrible if things go on like this!We know the sounds of cities are loud enough to cause great harm to people's hearing.

Noise pollution can cause just as many damaging effects on people's health as other forms of pollution. Exposure to excessive noise can cause hearing loss, stress, lack of sleep, irritability, indigestion, heartburn, high blood pressure and ulcers. In 1985, the Noise Control Act was enacted; however, the law is too lax and is seldom adequately enforced. Fortunately, the Environmental Protection Administration (EPA) plans to have amendments to the law passed by the end of the year. The revised law would prohibit building renovations and interior decorations at noon, and between 6:00 p.m. and 8:00 a.m. in residential areas. The EPA also plans to ban karaoke singing at home during lunchtime and from 10:00 p.m. to 8:00 a.m. Those who violate the amended law would be fined a maximum NT$30,000. Hopefully the revision to the Act will be passed as scheduled. More importantly, it must be strictly enforced. Authorities responsible for implementing the law, especially environmental protection authorities and the police, must never shirk their duties in enforcing legislation. Other steps should be taken to protect people from the damaging effects of environmental noise. Such steps include locating residential buildings as far from noise sources as possible, banning the honking of car horns in certain areas, and planting more trees in front of buildings to absorb noise.

Noise Pollution 噪音污染Noise is among the most pervasive pollutants today. Noise from road traffic, jet planes, jet skis, garbage trucks, construction equipment, manufacturing processes, lawn mowers, leaf blowers, and boom boxes, to name a few, are among the audible litter that are routinely broadcast into the air. Noise negatively affects human health and well-being. Problems related to noise include hearing loss, stress, high blood pressure, sleep loss, distraction and lost productivity, and a general reduction in the quality of life and opportunities for tranquillity. We experience noise in a number of ways. On some occasions, we can be both the cause and the victim of noise, such as when we are operating noisy appliances or equipment. There are also instances when we experience noise generated by others just as people experience second-hand smoke. While in both instances, noises are equally damaging, second-hand noise is more troubling because it has negative impacts on us but is put into the environment by others, without our consent. Noise pollution is not easily defined. Part of the difficulty lies in the fact that in some ways it is different from other forms of pollution. Noise is transient; once the pollution stops, the environment is free of it. This is not the case for chemicals, sewage, and other pollutants introduced into the air, soil, or water. The definition of noise itself is highly subjective. To some people the roar of an engine is satisfying or thrilling; to others it is an annoyance. Loud music may be enjoyable or a torment, depending on the listener and the circumstances. Broadly speaking, any form of unwelcome sound is noise pollution, whether 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 that have to be considered 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. The decibel (dB) (分贝) is a measure of sound intensity; that is, the magnitude of the fluctuations in air pressure caused by sound waves. 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. There is fairly consistent evidence that prolonged exposure to noise levels at or above 80 dB can cause deafness. The amount of deafness depends upon the degree of exposure. Noise can cause annoyance and frustration as a result of interference, interruption and distraction. Exposure to noise is also associated with a range of possible physical effects including: colds, changes in blood pressure, other cardiovascular changes, increased general medical practice attendance, problems with the digestive system and general fatigue.
