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 trio of engineers named these bricks, “Cobogóâ€, for no other reason than to incorporate the first two letters of each of their last names into the name: “CO†“BO†and “GOâ€.
This is our satisfaction to receive these messages from each of our customers, one more job done successfully.

Mix and match TriSoft’s® available modules and nodes as building blocks to build faceted straight field layouts scalable to any size space.

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.
There are three things that can happen when sound hits a wall. It can be reflected, absorbed, or diffused. If the wall here is flat and hard, the sound will be reflected. A single strong reflection can sometimes be heard as an echo, but in most rooms a lot of reflections (including reflections of reflections) combine into the reverberation.
The absorption was brought along the side walls to soak up the standing wave. We wanted to keep the room symmetrical, so we spaced out the absorptive panels, winding up with a pattern where bare wall on one side was opposed by absorption on the other. A large section of absorptive wall near the left speaker created click here a dead corner for recording vocals.
We found the sound to be balanced read more in frequency when the walls were about one third covered with fiberglass.
Has a gift shop with many interesting more info products, Brasilia well made and alternative things. There's a café serving simple basics. Is a meeting place, and more informal meetings. Tip: carrot cake with chocolate is amazing! Shop prices are not so cheap, but who wants to buy a really nice souvenir of Brasilia is a tip.
