ELENA, Ordaz Castillo et al. Effects of noise exposure in working places on quality of life and performance. Med. segur. trab. [online]. 2009, vol.55, n.216, pp.35-45. ISSN 1989-7790.

Aims: Occupational noise exposure could produce extra-auditory effects. The purpose of this study was to investigate whether occupational noise exposure can influence human behaviour, performance and development of psychosomatic symptoms. Methodology: Cross-sectional study, from the Data-base of Spanish VI National Survey on Working Conditions, "noise exposure" has been analyzed as independent variable and: "symptoms self-reportered by workers" as effect variable, considering them independently or grouped variables in behavioural, psychosomatic and performance symptoms. The relationship between exposure and effect was analyzed by X2 test. Prevalence adjusted Odds Ratio by work rhythm (95% CI), were estimated to measure the association between perceived noise annoyance and grouped symptoms in the population and in the different branches of activity. Results: 36.5% of the working population is exposed to noise in their workplace. There is a higher prevalence of behavioural symptoms group, psychosomatic and performance (p <0.001) among workers exposed to noise compared to unexposed. Health Care Sector reported the highest risk for behavioural (OR=2,53 [1,71-3,75]) and performance symptoms(OR=2,26, [1,43-3,56]) . Chemical Industry had a prevalence ratio between noise and psychosomatic symptoms of (OR=5,37 [1,13-25,55]). Conclusions: Our results found and statistic significant association between noise annoyance exposure and behavioural, performance and development of psychosomatic symptoms in the Spanish working population.
