Análise do projeto do tubo de impedância do laboratório de mecânica aplicada da Universidade Federal de Goiás baseado na norma ISO 10534-2. 2023. 59 f. Trabalho de Conclusão de Curso (Bacharelado em Engenharia Mecânica) - Escola de Engenharia Elétrica, Mecânica e de Computação, Universidade Federal de Goiás, Goiânia, 2023.http://repositorio.bc.ufg.br/handle/ri/23420The objective of this work is to analyze the experimental apparatus of the impedance tube of Laboratório de Mecânica Aplicada (LabMEC), of Escola de Engenharia Elétrica, Mecânica e de Computação (EMC) of Universidade Federal de Goiás (UFG), which experimental routine is stated by the norm ISO 10534-2/1998, and with that identify potential problems caused by non-compliant items between ISO and prototype construction. After identifying them, an intervention proposal was made with the manufacture of new parts, and with that a series of measurements were made involving two samples of acoustic foams, involving the original configuration of the impedance tube, as well as two new intervention proposal configurations. With the data in hand, they were compared in combinations of 2 in order to isolate the variables and observe separately the effect of the items in disagreement with the standard. It was possible to observe the change in the behavior of the results separately, and then as a whole.porAcesso AbertoAcústicaTubo de impedânciaCoeficiente de absorção sonoraAdequação normativaNorma ISO 10534-2Espuma acústicaAcousticsImpedance tubeSound absorption coefficientNormative adequationISO 10534-2Acoustic foamTCC
