Resumo
In the current project, the precision and reliability of an impedance tube recently built at the Department of Computational Mechanics (DMC) of the School of Mechanical Engineering (FEM) of
the University of Campinas (UNICAMP) was assessed and refinements were performed in the project in order to improve the overall quality of the results obtained. The major aspects of influence in the precision of the instrument were investigated and reported.
