The objective of this study is to assess occupational noise exposure in a metalworking company according to current legal regulations in order to reduce the impact on workers’ health. We carried out research with a descriptive, quantitative, and cross-sectional design. Study population is made up of 8 workers, intentionally selected by the company, who are exposed to noise levels likely to exceed the permissible limit and to significant noise episodes during the workday. A conventional REED brand sound level meter, model R8090, previously calibrated with an "A" weighting filter and slow response (SLOW), was used. The strategy and measurement of sound pressure levels at different workstations were guided by ISO 9612:2010 standards. According to the results of sound pressure level measurements in the metalworking company, workers involved in the disassembly of equipment and electronic parts are exposed to noise levels exceeding the permissible limits of 85 dBA established in Resolution 1792 of 1990 by the Ministry of Labor, which indicates a high probability of permanent hearing loss. We recommend future research regarding the loss of hearing capacity in workers with chronic exposure to high levels of occupational noise in the metalworking sector.
