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.

The soft volumetric geometry of the hollowed-out elements comprising the walls is a complex construction, made with infinite curved lines. The modular element, a work of art, was designed by the Austrian-American Erwin Hauer who, since 1950, has conceived and made sculptures for architectural space. His minimalist elements dialogue with the architecture and remind us of some traces of Brazilian modern architecture.
Some of this coloration is ok, even preferable, but eventually the room develops more info a here tubby response. If we need a very dead room and bass buildup occurs there are devices called bass traps and Helmholtz resonators that absorb a restricted range of very low frequencies. The specifics for designing these are beyond the scope of this article, but the general principle is the larger they are, the lower the frequency. The moral is that absorption should be used only in moderation, and only materials that soak up the full range of sound should be used.
