Abstract
This presentation will overview the development and application of three new active noise control technologies at VAL-Virginia Tech. Distributed Active Vibration Absorbers (DAVAs) consist of large area spring elements with embedded active elements and covered with a dynamic mass layer. Development of conformal DAVAs and their application to noise control in aircraft and launch vehicle fairings will be overviewed. New work in applying active control techniques to developing virtual acoustic systems and its application to virtual prototyping and virtual reality applications will be discussed. The development a modular, compact active noise control duct which utilizes very small active sources, transducers and a cost effective controller to reducing the total radiated sound from small fans will be presented. The application of the modular ANC duct to a small computer cooling fan will be presented.
