BAEZ R., Mirtha et al. Noise induced hearing loss in workers exposed in their work environment. An. Fac. Cienc. Méd. (Asunción) [online]. 2018, vol.51, n.1, pp.47-56. ISSN 1816-8949.


The noise-induced hearing loss is a real problem from the social and health point of view, due to its constant increase, as the civilization advances and develops. With industrialization and lack of awareness about its incidence, this condition is increasing day by day. It is estimated that one third of the world population suffers some degree of noise-induced affectation. It is important to know the prevalence because hearing-induced hearing loss is one of the main causes of preventable disability.


To identify the occupational risk in which workers are exposed to industrial noise, by measuring the degree of hearing loss in connection with their work environment and the study of the current situation of current regulations on occupational health, in order to elaborate proposals for the improvement of the situation detected.

Material and Methods:

Cross-sectional descriptive study with analytical component, taking as sample 109 workers from a media company of the city of Asunción, in the year 2017, in order to identify the prevalence of noise-induced hearing loss and its relationship with the factors that produce them.


A total of 109 workers from different sectors of a graphic communication company were studied. 49 workers presented sensorineural hearing loss, representing a prevalence of 45%.


There is a significant risk of hearing damage in workers exposed to noise pollution depending on the exposure of daily workload and taking into account that the nature of the injury is irreversible, it is necessary to improve the guidelines regarding preventive measures.


the principles of ethics are respected, preserving the identity of the evaluated workers. It respects the principles of beneficence since it can contribute to their auditory health as well as non-maleficence since this study does not present risks.
