Abstract
Summary Introduction: Noise exposure is one of the most common health risk factors, and workers are exposed to sound pressure levels capable of producing hearing loss. Aim: To assess the prevalence of hearing loss in the elderly and its possible association with a history of occupational noise exposure and with sex. Methods: A prospective study in subjects aged over 60 years. The subjects underwent anamnesis and audiological assessment. The Mann–Whitney test and multiple logistic regression, with 95% confidence interval and p < 0.05, were used for statistical analysis. Results: There were 498 subjects from both sexes, and the median age was 69 years. From the comparison between men and women, we obtained the medium hearing I (500, 1000, and 2000 Hz p = 0.8318) and the mean hearing II (3000, 4000, and 6000 Hz; p < 0.0001). Comparing the thresholds of individuals with and without a history of occupational noise exposure, we obtained the medium hearing I (p = 0.9542) and the mean hearing II (p = 0.0007). Conclusion: There was a statistically significant association between hearing loss at high frequencies and the risk factors being male and occupational noise exposure.
