Part 6 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 proctivity, and a general rection 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 introced 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 ration, 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) (分貝) 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.

通常所說的雜訊污染是指人為活動而不是自然現象引起的。雜訊污染是物理性污染，本身對人無害，只是在環境中的流量過高或過低時，才會造成污染或異常。物理性污染一般是局部性的，即一個雜訊源不會影響很大的區域。

另處，物理性污染沒有後效作用，即雜訊不會殘存在環境中，雜訊停止，污染立即消失。外界噪音污染主要來自航空、公路、鐵路運輸，以及工程施工和工業生產等;而室內噪音污染則來自風扇、電腦及其它家用電器。

噪音污染不但能夠影響人的聽力，而且能夠導致高血壓、心臟病、記憶力衰退、注意力不集中及其它精神綜合征。研究表明，人聽覺最高可以接受30分貝的音量，當室內的持續噪音污染超過30分貝時，人的正常睡眠就會受到干擾，而持續生活在70分貝以上的噪音環境中，人的聽力及身體健康將會受到影響。

世界衛生組織(WHO)最近就全世界的噪音污染情況進行了分析調查，認為全球噪音污染已經成為影響人們身體健康和生活質量的嚴重問題，呼籲世界各國積極採取有效措施來控制減少噪音污染。

為此，他們建議各國政府將治理噪音污染納入國家的環保計劃，將衛生組織的指導性標准視為噪音治理的長期目標，制定和實施有關噪音管理的法律法規，支持有關減少噪音的科學研究，

制定和完善有關噪音的測量標准，鼓勵有關噪音對環境和健康影響的研究，進一步加強有關噪音污染的宣傳，讓全社會重視噪音污染的危害，減少噪音污染對人類健康的影響。
