Acesso em:.https://repositorio.ufpa.br/handle/2011/12871The Lake Tucuruí Integration Region (RI) stands out for its banana production in the state of Pará, making it one of the main producers of the fruit. However, the income of farmers in the region with banana production is restricted only to the sale of the fruit, discarding the other parts of the banana tree, which can be used to manufacture products with higher added value. With the use mainly of the fibers of the banana pseudo-stem, several products can be generated, boosting the development of banana cultivation in the region and promoting an increase in employment and income. Aiming at this socioeconomic growth of the RI Lago de Tucuruí, the present work presents, in its first part, an analysis of the fiber extraction machine of the banana pseudo-stem at the Federal University of Pará, Campus de Tucuruí, which will serve the small producers and cooperatives of farmers in the region. In the operation of the machine, it was found that it has noise problems. The sound pressure levels measured around the machine are above the normative limits. Thus, studies were carried out to define acoustic solutions aimed at solving the problem. In the second part, the main focus of this work is to present the acoustic solutions for the fiber extraction machine, including the specification of vibration isolators, replacement of the electric motor fan and dimensioning of the partial enclosure of the machine.Acesso Abertohttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Controle de ruídoMáquinas-ferramentaAgriculturaDissertaçãoCNPQ::ENGENHARIASTECNOLOGIA E MEIO AMBIENTETECNOLOGIAS SUSTENTÁVEIS
