调查243名在航空站附近居住,工龄10年以上,年龄30～59岁的健康人。分两组,A组由120名航空机械基地的维修技工组成,露天机场工作时航空噪声强度为92～116分贝,超过容许强度(85分贝),约一半时间在辅助车间工作,噪声强度为70～85分贝。并受场强为40～1500微瓦/厘米~2的微波作用,工人无防护设施。B组(117人)为附近修理厂的技工及修理工,工作时航空噪声及车间噪声
A total of 243 healthy people aged 30 to 59 years who lived in the vicinity of the airport were surveyed over the age of 10 years. There are two groups. Group A consists of 120 mechanics of aviation machinery bases. The noise intensity of open air airport is 92-116 dB when it exceeds the allowable intensity (85 decibels), and about half of the time is spent in the auxiliary workshop with a noise intensity of 70 ~ 85 dB. And by the field strength of 40 ~ 1500 microwatts / cm ~ 2 microwave, workers without protective facilities. Group B (117) was a mechanic and repairman at a nearby repair shop. Aviation noise and workshop noise
