In this paper, the acoustic impedance of a liner is educed by a novel semi-analytical inverse technique. The liner sample is placed flush with the solid walls in a rectangular duct with grazing flow. The technique uses complex acoustic pressure measured at four positions at the wall of the duct, upstream and downstream of the lined section, and edu

‘We developed a special floor made of cobogó brick filled with concrete; a fully experimental work that resulted in a beautiful pattern,’ explains Humberto. ‘We employed sisal fiber as a natural background that complements the strong graphic effect created by the cobogó brick.The paper deals with the setting up and test fli

So much has changed. When you get older, you look back on tensions and grievances and have another perspective on it. I think our relationship now is better than it's ever been. I would even describe it as great.Now that he’s staying on the sidelines while his bandmates revive their incendiary songs with help from Chuck D and B-Real during a

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
