　　Lesson 31 Non-auditory Effects of Noise 噪音的非听觉效应

Many people in industry and the Services, who have practical experience of noise, regard any investigation 1 of this question as a waste of time; they are not prepared even to admit the possibility that noise affects people. On the other hand, those who dislike noise will sometimes use most inadequate 2 evidence to support their pleas for a quieter society. This is a pity, because noise abatement 3 really is a good cause. and it is likely to be discredited 4 if it gets to be associated with bad science.

One allegation often made is that noise produces mental illness. A recent article in a weekly newspaper, for instance, was headed with a striking illustration of a lady in a state of considerable distress 5, with the caption 6 'She was yet another victim, reduced to a screaming wreck 7 '. On turning eagerly to the text, one learns that the lady was a typist who found the sound of office typewriters worried her more and more until eventually she had to go into a mental hospital. Now the snag in this sort of anecdote 8 is of course that one cannot distinguish cause and effect. Was the noise a cause of the illness, or were the complaints about noise merely a symptom? Another patient might equally well complain that her neighbours were combining to slander 9 her and persecute 10 her, and yet one might be cautious about believing this statement.

What is needed in the case of noise is a study of large numbers of people living under noisy conditions, to discover whether they are mentally ill more often than other people are. The United States Navy, for instance, recently examined a very large number of men working on aircraft carriers: the study was known as Project Anehin. It can be unpleasant to live even several miles from an aerodrome; if you think what it must be like to share the deck of a ship with several squadrons of jet aircraft, you will realize that a modern navy is a good place to study noise. But neither psychiatric interviews nor objective tests were able to show any effects upon these American sailors. This result merely confirms earlier American and British studies: if there is any effect of noise upon mental health it must be so small that present methods of psychiatric diagnosis 11 cannot find it. That does not prove that it does not exist; but it does mean that noise is less dangerous than, say, being brought up in an orphanages--which really is a mental health hazard.
