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.

This phenomenon can be prevented by designing the room with nonparallel walls. It can be cured in existing rooms by making one of the walls absorptive or by breaking up the flat surfaces.
The curved lines, designed with perfection nod to the architecture of Brasilia by Niemeyer; furthermore, the concrete modules descend from the Cobogós, which lends its name to the house, created in Recife and diffused by Lucio Costa in delicate references to colonial architecture.
Reflections off flat walls can sometimes combine to produce undesirable effects. The worst of these is the standing wave.
