Example Section H viii Research on earphones harm Beyond comfortable of hearing The maximum noise level of the 'Walkman' Harmful noise pollution Noise everywhere Reasons for harm The maximum safe noise dosage The curse of silence A cure for 'tinnitus' Alarming statistical evidence A chronic hearing loss impairment The danger of falling asleep
A It is by old saying that the virtue of silence by claiming it is golden, yet experience tells us that silence is as hard to come by as the precious metal itself. The benefit of silence to the human ear is scientifically demonstrable. Less superfluous noise; less impairment to the hearing. Yet this precious commodity is no longer valued. Noise is ever present in modern life and is an accumulative experience. The ill effects of noise pollution are of two kinds: acute -- exposure to an individual instance of a very loud noise, such as a gunshot or explosion; and chronic -- the experience of too much noise over an extended period of time.
B City and urban dwellers exist in an increasingly noise-ridden environment, and it is now almost impossible to escape exposure to high noise levels. Even if we exclude the more obvious sources of noise pollution such as jet plane engines, road works, power tools, loud music at dance parties and so on, it is clear that noise is a constant and often unwelcome companion. We have only to walk through a suburban shopping mall or department store, or catch a bus or train to be subjected to noise levels that a few decades ago would have been considered beyond human endurance. The popular practice of 'layering' sound, by adding a louder source of noise to that which already exists in order to mask it, merely compounds the problem. Because of the accumulative nature of noise abuse, constant noise is worse than noisy periods interspersed with silence.
C Our noise level acceptance threshold is rising in step with the number of persons developing hearing problems. Data available from a recent survey conducted by the Australian Bureau of Statistics show that 7.4% of people over 14 years of age have some discernible hearing problem. According to the survey, 24.6% of the 7.4% of persons with affected hearing have problems caused by subjection to a constant barrage of noise, either at work, in the everyday living environment, or as the result of a particular choice of leisure activity. The problem is most severe for males aged between 25 and 64 years of age, 9.1%of whom have a hearing disability, and for which the cause is constant noise in 44.4% of cases.
D Of current concern to acoustical engineers and psychologists at the National Acoustics Laboratories in Sydney, Australia, is the potential for damage to the eardrum caused by the transmission of loud sound through earphones placed directly into the ear canal. An almost universal fad among young people, the pocket-sized radio-cassette player (commonly known by the brand name 'Walkman') may be exposing its owner to greater than the maximum safe dosage of noise recommended for industrial workers - 90 decibels* over a period of 8 hours. This dosage, called Dose 1, can be achieved much sooner by exposing the ear to only slightly more than 90 decibels. Increases to the decibel level logarithmically shorten the exposure time required to reach a given dose. For instance, to achieve Dose 1 in 4 hours, it is necessary to raise the decibel exposure level by a mere 3 decibels.
E One danger posed to young ears is that the peak sound level from these radio-cassette players is often far too great; at high volume it is all too easy to receive Dose 1 in a short period of time. Any further noise heard above 90 decibels that day and the recipient is causing measurable damage to his or her ears. Another danger is the likelihood of a change in the pain threshold of noise resulting in users compensating by increasing the volume to levels way above what is considered safe. Finally, insertable earphones block the ear canal, thereby further increasing the noise level absorbed.
F But perhaps the most alarming potential for danger caused by insertable earphones is the ease with which the listener can exceed the safe time length of exposure to noise. The small earphones can be comfortably worn for extended periods of time. What is more, there is the danger of falling asleep with the earphones inserted, leading to an accumulation of excess noise while unconscious. G Noise abuse soon leads to varying degrees of hearing loss. What may begin as an acute temporary condition, in time becomes a chronic and irreversible disability. A common complaint
is 'tinnitus', or a 'ringing in the ears' which fails to subside after the ears are subjected to a short but extreme dose of noise. It is an exhausting condition that can seriously threaten the composure of the sufferer who can be driven to near madness. It is believed the composer Beethoven was particularly aggravated by this malady. At present, there is little that can be done in the majority of cases, although the victim might be able to obtain some temporary relief by using am asking device which blocks out the offending frequencies of sound with other, less annoying frequencies. H Inevitably, though, years of excessive noise accumulation take their toll and partial or complete deafness results. If silence is the cure for ailing ears (or, at least, the best way to prevent further deterioration of one's hearing), it is sobering to realise that it is also the unfortunate and permanent curse of a lifetime of noise abuse caused by ignoring the warnings.

The Darling Pit
A Situated in the Great Barrier Mountains, near the headwaters of the Darling River, is one of Australia’s earliest industrial monuments, the Darling Pit. Darling Pit is mine that started industrial development in Australia, Providing coal to power the factories, help run ships and the railways, make steel and heat homes.
B Begun in 1809 on Paul Darling’s farmstead when resources of coal and iron were found near the
surface, the Darling Pit was rapidly transformed from a simple drift mine into the Word’s biggest, and deepest, coal mine. 94miles of tunnels extending up to 600 feet below ground were all dug by hand. At its height in 1850,over 15,000 men were employed in the pit and it produced over 1.5 million tons of coal annually. It continued as a working mine until 1978 and is now preserved as museum and a monument to the men who worked here
C A glance from the surrounding hillside as you approach the Darling will show you how mining transformed the local scenery as well as the local economy. The Darling Pit retains its 19th century ironworks, pit head machinery, 3,000 terraced houses built to accommodate the workforce, a chapel and 4 pubs. Even the original farmhouse survives. This tight-knit community is now surrounded by slag heaps – the mountains of soil and other waste dug out to get to the coal.
D Mining was a dangerous occupation in the 19th century. Most mines suffered deaths from tunnel collapse and from flooding. Pneumoconiosis, an inflammation of the lungs brought about by prolonged exposure to coal dust, was also a common problem and historical works from the last century refer to the ease of identifying examiners by the ‘Darling cough’. The major problem in the Darling mine, however, was the prevalence of inflammable coal gas in the area, which resulted in the underground explosions of 1854 and 1910. Monuments to the 485 miners who died in these tragedies can be seen in the chapel.
E The Darling Pit is still a real colliery, even though it no longer produces coal. There is still a staff of over 100 who maintain the mine and assist the visitors. The Pit now allows tourists and visitors to undertake guided tours of the works, including a tour of selected shafts underground. Many of the guides are ex-miners who will explain the workings of the mine and tell you many stories from their personal experience. Helmets, lamps and protective clothing are provided, although visitors are reminded that it can(本文来自：Www.dXF5.com 东星资源 网:安阳环球雅思) be cold underground and they are advised to wear something warm as well as sensible protective footwear.
F The Darling Pit now has all the amenities needed for a major tourist attraction. Many of the buildings on the surface are open for exploration: the engine house at the pit head, the blacksmith’s shop, the pit head baths and the stables ( remember pit ponies provided much of the power for moving coal before the electric engine became available ). The miners’ pubs now feature as canteens and restaurants, offering a range of fast and high quality food and drink. There are picnic areas, toilets, a gift shop and even a photographic studio. The miners’ chapel is also available for those who would like to spend time in quiet contemplation or prayer.
G It is regretted that children under 5 cannot be taken on tours underground, although they can visit all the surface exhibits. Visitors in wheelchairs can be accommodated, even underground, but please notify the ticket office of this on entry.
H Opening hours are 9.30 am to 5.00 pm daily in summer from the beginning of April to the end of September. During winter opening is from 10.00 am to 4.00 pm. The site is open every day including weekends and bank holidays except for Christmas Day. Please note, however, that the underground section of the Pit may be closed for maintenance during the winter and visitors should ring in advance to avoid disappointment. Underground tours start from 10.00 am in the summer and 11.00 am in winter and last admissions are at 3.30 pm throughout the year. A complete tour will take at least 3 hours and could last all day. Group rates are available, as are concessions for school parties and OAPs. There is a free car park.
