[00:03.22]Non-auditory effects of noise
[00:11.01]What conclusion does the author draw about noise and health in this piece?
[00:18.19]Many people in industry and the Services,
[00:21.21]who have practical experience of noise,
[00:23.99]regard any investigation of this question as a waste of time;
[00:28.67]they are not prepared even to admit the possibility that noise affects people.
[00:34.56]On the other hand,
[00:35.97]those who dislike noise will sometimes use most inadequate evidence
[00:40.50]to support their pleas for a quieter society.
[00:44.39]This is a pity, because noise abatement really is a good cause,
[00:50.12]and it is likely to be discredited if it gets to be associated with bad science.
[00:56.80]One allegation often made is that noise produces mental illness.
[01:02.85]A recent article in a weekly newspaper, for instance,
[01:06.37]was headed with a striking illustration of a lady in a state of considerable distress,
[01:12.20]with the caption 'She was yet another victim, reduced to a screaming wreck'.
[01:19.25]On turning eagerly to the text, one learns that the lady was a typist
[01:24.54]who found the sound of office typewriters worried her more and more
[01:28.84]until eventually she had to go into a mental hospital.
