Occupational noise and blood pressure variation

Abstract EN

Previous studies have demonstrated association between exposure to occupational (workplace) noise and blood pressure.

The goal of the present research was to investigate a relationship between noise exposure and blood pressure among 1374 workers from 12 companies.

Based on a confidence level of 95% (a = 0.05), 175 workers as a case group and 174 as a control group were randomly selected.

In addition, the participants were divided into different age and work experience groups.

The results revealed that noise levels in most of companies exceeded the NIOSH (1998) standard.

They also show a significant statistical relationship between exposures to occupational noise level >100 dBA (^-weighted decibel), hypertension and work experience >4 years.

It was concluded that to study an association between exposure to workplace noise and blood pressure, length of time on job must be taken into consideration.
