Maturity level of hearing conservation programs in metallurgical companies and the workers noise perception
This research aimed to evaluate the influence of level maturity about hearing conservation programs on the workers risk perception. This study evaluated five metallurgical companies with a sample of 243 workers exposed to sound pressure levels above the action level in national legislation 85 dB (A). Based on the bibliographic review, two questionnaires were used to evaluate qualitative variables. The first questionnaire was developed and applied to companies to evaluate maturity levels in hearing conservation programs. Subsequently a questionnaire was applied to the worker considering the individual noise perception; It was concluded that the different levels of maturity in hearing conservation program presented no significant differences in the workers perception, however, there has been an increased risk perception in the different levels of exposure to noise.
