  READING PASSAGE 3

  You should spend about 20 minutes on Questions 27- 40, which are based on Reading Passage 3below.

  EFFECTS OF NOISE

  In general, it is plausible to suppose that we should prefer peace and quiet to noise. Andyet most of us have had the experience of having to adjust to sleeping in the mountains orthe countryside because it was initially 'too quiet', an experience that suggests that

  humans are capable of adapting to a wide range of noise levels. Research supports thisview. For example, Glass and Singer (1972) exposed people to short bursts of very loudnoise and then measured their ability to work out problems and their physiological

  reactions to the noise. The noise was quite disruptive at first, but after about four minutesthe subjects were doing just as well on their tasks as control subjects who were not ex posedto noise. Their physiological arousal also declined quickly to the same levels as those ofthe control subjects.

  But there are limits to adaptation and loud noise becomes more troublesome if the personis required to concentrate on more than one task. For example, high noise levels interferedwith the performance of subjects who were required to monitor three dials at a time, a

  task not unlike that of an aeroplane pilot or an air-traffic controller (Broadbent, 1957).Similarly, noise did not affect a subject's ability to track a moving line with a steeringwheel, but it did interfere with the subject's ability to repeat numbers while tracking(Finkelman and Glass, 1970).

  Probably the most significant finding from research on noise is that its predictability ismore important than how loud it is. We are much more able to tune out' chronic

  background noise, even if it is quite loud, than to work under circumstances with

  unexpected intrusions of noise. In the Glass and Singer study, in which subjects were

  exposed to bursts of noise as they worked on a task, some subjects heard loud bursts andothers heard soft bursts. For some subjects, the bursts were spaced exactly one minuteapart (predictable noise); others heard the same amount of noise overall, but the bursts

  occurred at random intervals (unpredictable noise). Subjects reported finding the

  predictable and unpredictable noise equally annoying, and all subjects performed at aboutthe same level during the noise portion of the experiment. But the different noise

  conditions had quite different after-effects when the subjects were required to proofreadwritten material under conditions of no noise. As shown in Table l the unpredictable

  noise produced more errors in the later proofreading task than predictable noise; and soft,unpredictable noise actually produced slightly more errors on this task than the loud,

  predictable noise.

  Apparently, unpredictable noise produces more fatigue than predictable noise, but it takesa while for this fatigue to take its toll on performance.

  Predictability is not the only variable that reduces or eliminates the negative effects of

  noise. Another is control. If the individual knows that he or she can control the noise, thisseems to eliminate both its negative effects at the time and its after-effects. This is true evenif the individual never actually exercises his or her option to turn the noise off (Glass andSinger, 1972). Just the knowledge that one has control is sufficient.

  The studies discussed so far exposed people to noise for only short periods and only

  transient effects were studied. But the major worry about noisy environments is that livingday after day with chronic noise may produce serious, lasting effects. One study, suggestingthat this worry is a realistic one, compared elementary school pupils who attended schoolsnear Los Angeles's busiest airport with students who attended schools in quiet

  neighbourhoods (Cohen et al., 1980). It was found that children from the noisy schoolshad higher blood pressure and were more easily distracted than those who attended thequiet schools. Moreover, there was no evidence of adaptability to the noise. In fact, thelonger the children had attended the noisy schools, the more distractible they became. Theeffects also seem to be long lasting. A follow-up study showed that children who were

  moved to less noisy classrooms still showed greater distractibility one year later than

  students who had always been in the quiet schools (Cohen et al, 1981). It should be notedthat the two groups of children had been carefully matched by the investigators so thatthey were comparable in age, ethnicity, race, and social class.
