4、orrected for railway,noise exposure.,8,transportation noise and blood pressure,Railway and traffic noise differ in frequency,slope of rise,and absolute levels of noise.,Traffic noise from heavily frequented streets,corresponds to a continuous exposure without much variation in noise exposure levels,
5、whereas railway noise is characterized by a discontinuous pattern of intermittent very high maximum sound pressure levels and steep slopes of rise.,The intermittent pattern of noise exposure is thought to be more disruptive.,railwaytraffic&nightday,discussion,频率高,坡度大,声音大,9,transportation noise and b
