Brief summary

to perform a comparative study, through audiometrics tests, of workers exposed to noise only as well as noise associated to the chemical products. The hypothesis is that the Group II will have higher prevalence of occupational hearing loss when compared to group I.

Interventions

to perform a comparative study, through audiometrics tests, of workers exposed to noise only as well as noise associated to the chemical products. 71 metallurgists exposed to noise and chemical products (group II) for a period that varies from 3 to 20 years.The workers were exposed to noise from heavy machinery and chemicals such as styrene, acetone, resin, cobalt, among others.
