Introduction: Noise is the main labor risk and constitutes a public health problem. The purpose of this study was to examine the relationship between noise at the workplace and acoustic trauma and noise-induced hypoacusia. Methods: An observational, prospective and transversal study was carried out on 116 workers of an asphalt factory in Mexico City, Mexico. Descriptive statistical analysis was carried out, and Spearman's rank correlation was run to determine the relationship between years of exposure, decibels and acoustic trauma. Results: Correlation between years of exposure and degree of hypoacusia was low (Spearman's rho 0.3281). The correlation between years of exposure and type of acoustic trauma was also low (Spearman's rho 0.3514). Discussion: Correlation between years of exposure to noise at the workplace and hearing loss is low. Other factors, such as genetic susceptibility, are important. Hearing loss prevention programs should be instituted in workplaces with high noise levels to prevent noise-induced hearing loss as well as other health effects related to noise exposure.
