Hearing problems in english

Noiseis 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,

Paragraph 1 (Q.1) The old adage extols the virtue ofsilence by claiming it is

golden, yet experience tells us thatsilence is as hard to come by as the precious metal itself Thebenefit of silence to the human ear is

scientificallydemonstrable Less superfluous noise; less impairment to

thehearing Yet this precious commodity is no longer valued Noiseis 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 asa gunshot or explosion; and chronic - the experience of too muchnoise over an extended period of time

Paragraph 2 (Q.2) City and urban dwellers exist in anincreasingly noise-ridden

environment, and it is now almostimpossible to escape exposure to high noise levels Even if weexclude the more obvious sources of noise pollution such as jetplane engines, road works, power tools, loud music at danceparties and so

on, it is clear that noise is a constant and oftenunwelcome companion We have only to walk through a suburbanshopping mall or department store, or catch a bus or train to besubjected to noise levels that a few decades ago would have beenconsidered beyond human endurance The popular practice of

'layering'sound, by adding a louder source of noise to that which alreadyexists

in order to mask it, merely compounds the problem Becauseof the

accumulative nature of noise abuse, constant noise isworse than noisy periods interspersed with silence

Paragraph 3 (Q.3) Our noise level acceptance thresholdis rising in step with

the number of persons developing hearingproblems Data available from a recent survey conducted by theAustralian Bureau of Statistics show that 7.4%

of people over 14years of age have some discernible hearing problem

According tothe survey, 24.6% of the 7.4% of persons with affected

hearinghave problems caused by subjection to a constant barrage of noise,either

at work, in the everyday living environment, or as theresult of a particular choice of leisure activity The problem ismost severe for males aged between

25 and 64 years of age, 9.1%of whom have a hearing disability, and for which the cause isconstant noise in 44.4% of cases

Paragraph 4 (Q.4) Of current concern to acousticalengineers and psychologists

at the National AcousticsLaboratories in Sydney, Australia, is the potential for damage tothe eardrum caused by the transmission of loud sound

throughearphones placed directly into the ear canal An almost universalfad among young people, the pocket-sized radio-cassette player (commonlyknown

by the brand name 'Walkman') may be exposing its owner togreater than the maximum safe dosage of noise recommended forindustrial workers - 90

decibels* over a period of 8 hours Thisdosage, called Dose 1, can be achieved much sooner by exposingthe ear to only slightly more than 90 decibels

Increases to thedecibel level logarithmically shorten the exposure time

requiredto 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 3decibels

Paragraph 5 (Q.5) One danger posed to young ears isthat the peak sound level

from these radio-cassette players isoften far too great; at high volume it is all too easy to receiveDose 1 in a short period of time Any further noise heard above90 decibels that day and the recipient is causing measurabledamage to his

or her ears Another danger is the likelihood of achange in the pain threshold of noise resulting in userscompensating by increasing the volume to levels way above what isconsidered safe Finally, insertable earphones block the earcanal, thereby further increasing the noise level absorbed

Paragraph 6 (Q.6) But perhaps the most alarmingpotential for danger caused

by insertable earphones is the easewith which the listener can exceed the safe time length ofexposure to noise The small earphones can be comfortably wornfor extended periods of time What is more, there is the dangerof falling asleep with the earphones inserted, leading to anaccumulation of excess noise while unconscious

Paragraph 7 (Q.7) Noise abuse soon leads to varyingdegrees of hearing loss

What may begin as an acute temporarycondition, 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 shortbut extreme dose of noise It is an exhausting condition that canseriously threaten the

composure of the sufferer who can bedriven to near madness It is believed the composer Beethoven wasparticularly aggravated by this malady At present, there islittle that can be done in the majority of cases, although thevictim might

be able to obtain some temporary relief by using amasking device which blocks out the offending frequencies ofsound with other, less annoying frequencies

Paragraph 8 (Example) Inevitably, though, years ofexcessive noise

accumulation take their toll and partial orcomplete deafness results If silence is the cure for ailing ears(or, at least, the best way to prevent further deterioration ofone's hearing), it is sobering to realise that it is also theunfortunate and

permanent curse of a lifetime of noise abusecaused by ignoring the warnings

3.Writing

Writing Task 1:

The diagrams show data for a flu epidemic which hit a large country town in

1996 Figure 1 gives the number of persons who died; Figure 2 shows the percentage breakdown of females who received a new flu vaccine; and Figure 3 gives the number of cases of flu before and during the epidemic

In Figure 1 it can be seen that the flu was responsible for the deaths of 2

females but no males in the period from March to May However, from June to August, there were 4 female deaths and 1 male death

According to the pie chart in Figure 2, only those females most at risk were given the new flu vaccine; 28% did not take part in the trial Of those females who took part, 35% were aged (over 65 years old); 24% were babies or

children; and 13% were either hospitalised or receiving other medical attention
