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.
As Cebgo is owned by airline Cebu Pacific, passengers can check-in em linha for their Cebgo flights via the Cebu Pacific website. This service will close 4 hours in advance of flying for international flights, and 1 hour prior for domestic flights.
Este difusor Muito mais simples do construir é uma superfÃcie encurvada tal como a indicada na figura seguinte.

More attractive absorbers can be made from Insul-shield (a solid wall insulation material) or various foam products sold through audio supply houses. (Again see sidebar) These all work down to cem hz or so. Carpet on a thick pad is a decent absorber down to about 250hz. It is the simplest way to control floor to ceiling standing waves, and if hung in deep pleats works well as a wall treatment also.
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 check here made sculptures for architectural space. His minimalist elements dialogue with the architecture and remind us of some traces of Brazilian modern architecture.
Some website of this coloration is ok, even preferable, but eventually the room develops a 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 here full click here range of sound should be used.
In addition to its function, the cobogó brings a certain poetic feel to any architectural project. Here, we have highlighted this Brazilian creation, to briefly shed light on its history and to present a selection of projects that adopt this element.Â
In the house, there is a great concern to use recycling apparatus and reduce water consumption; rationalize and organize the construction to minimize the impacts; use devices for energy efficiency and optimization; install solar heating plaques; besides using only certified, recycled or ecologically correct material. The use of this knowledge together with architecture that respects the local climate resulted in a house having excellent inner comfort.
