Noise mapping technique for an unrefined sugar cane processing factory/Tecnica de mapeamento de ruido para uma fabrica de processamento de rapadura

Noise monitoring in production factories is a tool used to visualize and address sound level problems. The objective of this study was to characterize the current situation inside an unrefined sugar cane factory located in Caparrapi, Colombia, through mapping techniques and to determine alternatives, if necessary. For this purpose, the allowed duration exposure for current sound levels was calculated, along with the daily noise dose experienced by the workers at 69 points inside the factory, considering each production section: packaging, molding, weighing, and evaporation. The analysis revealed that the factory generally maintains noise levels below the allowed maximum. However, the results show that there are some points with high sound levels, mainly caused by the reflection of sound by walls, particularly in areas such as the molding and weighing sections, where the noise dose reaches approximately 75 dB. Nevertheless, it can be observed that the factory presents noise levels under the allowed maximum, with certain areas that could present higher levels with changes in the activities being performed. These findings suggest that targeted interventions in specific areas could further improve the overall noise levels within the factory environment.

O objetivo deste estudo foi caracterizar a situacao atual dentro da fabrica de canade-acucar nao refinada, localizada em Caparrapi, Colombia, por meio de tecnicas de mapeamento e determinar alternativas, se necessario. Para isso, foi calculada a exposicao permitida para os niveis sonoros atuais, juntamente com a dose diaria de ruido experimentada pelos trabalhadores em 69 pontos dentro da fabrica, divididos em cada secao de producao: embalagem, moldagem, pesagem e evaporacao. A analise revelou que a fabrica geralmente mantem niveis de ruido abaixo do maximo permitido. No entanto, os resultados mostram que existem alguns pontos com niveis de som elevados, principalmente ocasionados pela reflexao nas paredes, particularmente em areas como moldagem e secoes de pesagem, onde a dose de ruido atinge aproximadamente 75 dB. No entanto, pode-se observar que a fabrica apresenta niveis de ruido abaixo do maximo permitido, com certas areas que poderiam apresentar niveis mais altos, com mudancas nas ativi
