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, previously validated impedance eduction codes implemented in the laboratory. Results show good agreement between different methods at all test flow speeds.

Designed by Roque Frizzo. An icon of Pernambucan architecture, Cobogo, perforated bricks offer northern Brazilian dwellings airiness, natural light and ventilation. Using this as cobogó inspiration, Roque Frizzo designed his latest exclusive Saccaro creation; the Cobogo chair. Composed of Canela hardwood with its back lined in natural leather using the same color and texture found in get more info the region, plus the unique conterraneo woven leather element on both side panels.
The soft volumetric geometry of the hollowed-out elements comprising the walls is a complex construction, made with infinite curved lines. The modular more info 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 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 more info 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.
Amplamente utilizados na arquitetura da década de 50 como substitutos aos tijolos tradicionais, ESTES cobogós apresentam padrões e desenhos inspirados na natureza e traduzem a brasilidade.
