在社会噪声问题上,运输事业为一重要方面,特别值得注意的是与载重货车直接有关的噪声污染。最早的兴趣只限于对州间商业(inter-state commerce)中的汽车为主的车辆外噪声的管理规定,但同样也应重视货车产生的内噪声强度及其对司机听力潜在的有害影响。Close(1972) ,Seiff(1973) 等发现,大多数通用商业货车的内噪声,共强度往往超过90分贝A,在这种噪声允许极限内工作一天(八小时)之后,对多数货车司机的听力是有害的,因此,
Transport is an important aspect of social noise. Of particular note is noise pollution that is directly related to truckloads. Earliest interests were limited to the regulation of car-based out-of-town noise in inter-state commerce, but the same should also be given to the noise level inherent in trucks and their potential detrimental impact on drivers’ hearing. Close (1972), Seiff (1973) and others found that the noise of most GMVs often exceeds 90 decibels (A) in total noise, hearing most truck drivers after working one day (eight hours) within this noise tolerance Is harmful, therefore,
