Accoustical System Modules are built from our Soft Sound® acoustical material, which can provide an NRC rating of up to .90. Couple that with the system's angular faces and modularity to achieve amazing acoustical performance across an entire space or simply over a desired zone.The trio of engineers named these bricks, “Cobogó”, f

(There are some inexpensive models by Gold Line/loft or Radio Shack.) As

New microphone mountings designed to reduce flow noise by recessing the microphones and covering the cavities will also be described, and their flow noise levels compared to flush-mounting the microphones. Typical honeycomb core, perforated face-sheet liner samples were tested at different flow speeds at FLIR. Results were fed to multiple, previous

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 Emb

* In this case it is an entire panel, which is not made by modules like the traditional Brazilian cobogós. This is one of the first results obtained from the series of modular panels "Continua", created by Erwin Hauer and elaborated through digital means, including CATIA software, developed by Gehry Technologies.For best results, use the customi
