relationship between noise-exposure and absence from work

In a retrospective study, recorded work injuries and absenteeism during the year 1992 were studied among textile workers. 189 workers exposed to high sound level above 95 dB [A] - [EG] and 189 reference workers exposed to less noisy area - below 80 dB [A] - [RG]. The prevalence of injuries were twice in the EG [36.6%] than in the RG [19.6%]. Absenteeism was higher in BC than in the RG. However, there was no significant difference between the two groups for diagnosed medical diseases except for accidents. Recommendation is given
