Noise reduction to prevent hearing problems in workers

Abstract

Noise in the workplace is one of the most frequent occupational hazards for which almost all workers were once exposed to this condition. Objective: Determine if preventive maintenance can reduce the noise to which workers are exposed. Methodology: Noise measurements were carried out with a previously calibrated 3M Sound Pro-SE Integrating Sound Level Meter before performing preventive maintenance on the machinery and after maintenance. Results: An average of 71.8±9.6 dBA was obtained throughout the company. In the production area it was 86.9±5.2 dBA. After performing maintenance on the machinery, the average in the company was 70.1±8.7 dBA, and in the production area 81.9±8.1 dBA, being statistically significant p=0.03. Conclusion: Preventive maintenance is of great importance since it gives us evidence that not only is the machinery functioning properly, but it also reduces the noise levels to which workers are exposed, reducing the probability of loss of work. hearing due to noise exposure.
