Introduction: The whole population depends direct or indirectly on public transportation for the improvement of the traffic and, with the accelerated growth of the big cities, it is only possible to supply this demand, by means of rail transportation. While performing their roles, these professionals, may present many health problems including hearing disabilities. Objective: This body of work was aimed at studying the prevalence of hearing alterations in a group of rail workers in the State of São Paulo. Method: 98 male rail workers, aged between eighteen and fifty years old and who had been working in the profession from ten to twenty-five years, were evaluated. The subjects replied to an anamnesis and the tonal audiometric were performed. The audiograms were classified according to the group criteria suggested by Fiorini (1994). Results: From the total number of exams performed, 57 subjects (58,2%)have audiograms within normal parameters (Group 1) and 41 subjects (41,8%) were classified as having audiograms that suggest Noise Induced Hearing Loss (NIHL) (Group 2). From 57 audiograms in group 1 (100%), 32 (56,1%) were classified within normal parameters, with unilateral etchings; 18 (31,6%) were classified within normal parameters, with bilateral etchings and 7 (12,3%) have shown audiograms within normal parameters. From 41 audiograms group 2 (100%), 32 (78%) have suggested bilateral NIHL and 9 (22%) have suggested unilateral NIHL, considering that the contra lateral eras have presented hearing within the normal parameters. The major hearing endangerment was found in the frequencies of 4 kHz and 6 kHz. The qualitative variables: time in the profession (0,022) and previous exposure to noise (0,046) have statistically influenced the results of the audiometric evaluation. Conclusions: The prevalence of hearing alterations within the studied population was of 41,8% and there were no statistically significant differences among the results of the audiometric evaluation and the leisure habits |
