EVALUATION OF THE NONSPECIFIC EFFECTS INDUCED IN WORKERS BY OCCUPATIONAL NOISE
Abstract:
Occupational noise is directly related to decreased work ability, and non-specific pathology induced by prolonged exposure continues to be a topical issue in the scientific debate. This paper deals with noise from the psycho-physiological hazard perspective, using as assessment tool a symptoms questionnaire with 24 items in a case-control study (N = 100). The results show statistical significance for 10 items (of which 5 items at p<0.01), especially for lower work ability, poor memory, fatigue and depression. Subjects exposed to noise are 1.6 times higher risk to develop nonspecific effects, often neglected in favour of effects on the auditory analyzer. We propose this questionnaire to be applied routinely by occupational health services in order to manage the workers’ health, along with other means of workplace health promotion.
