Lesson 25-3 Non-auditory effects of noise
It can beunpleasant to live even several miles from an aerodrome; if you think what itmust be like to share the deck of a ship with several squadrons of jetaircraft, 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 anyeffects upon these American sailors. This result merely confirms earlierAmerican and British studies: if there is any effect of noise upon mentalhealth, it must be so small that present methods of psychiatric diagnosiscannot find it. That does not prove that it does not exist: but it does meanthat noise is less dangerous than, say, being brought up in an orphanage --which really is a mental health hazard.
