One of the most efficient, cost effective and widely used approaches to reduce the tonal signature of aeronautic engine noise is the so-called liners-structures located in the internal walls of the nacelle (the external structure of the motor) that form an acoustic treatment. In the research project called "Silent Aircraft", funded by FINEP and Embraer S.A. and involving some Brazilian universities, including the Federal University of Santa Catarina (UFSC), an extensive study has been conducted to better understand the behavior of such elements, as well as to predict its effect on engine noise.
