Industrial Noise in Nigeria: Measurements, Analysis, Dose and Effects

摘要

Industrial noise pollution has been assessed in 27 industries in south-eastern Nigeria. A total of 750 workers were contacted with working schedules of 6-12h/day, over 5 working days and with exposure times that varied between 0 second and 37.5 minutes were contacted. Noise exposure ratings of greater than unity were found in over 20 of the industries. Although almost all the workers contacted wanted occupational noise pollution controlled because of its various effects on them, a few still responded that they liked occupational noise. This gives credence to the assertion that ignorance of the irreversible nature of the far-reaching and wide-ranging effects of environmental noise pollution could yet be one reason for the "willing" exposure of the industrial plant workers to occupational noise.
