Abstract
This study presents an assessment of occupational noise exposure in welders using welding processes like coated electrodes, MIG, MAG and TIG in the Metallic Materials Characterization Laboratory (LCAM) of the Federal University of Pará (UFPA). The aim of the research was to analyze if the welders are exposed to noise levels above the limits established by NR 15 operations and unhealthy activities). In addition, there is also exposure suffered by other potential partners in different locations of the welding laboratory. In this context, it is of great relevance for this research relate the concepts of acoustics and vibrations in machines with the security area of work. Besides that the absence in some cases of need, the ear protectors were poorly dimensioned in relation to the necessary attenuation levels, leading to insufficient protection and even to the overprotection of the welder
