Real time control prototyping system for acoustic and vibration applications

There are certain classes of problems in acoustics and vibrations that require powerful real-time control systems able to process data over a large number of input and output channels. This is the case of active control problems (where carefully adjusted interference is used to cancel unwanted noise or vibration) andsound field synthesis (where we seek to physically reproduce a virtual sound field in an arbitrary environment using a set of reproduction loudspeakers). This proposal submitted by 4 researchers from the Groupe d'Acoustique de l'Université de Sherbrooke (GAUS) is to acquire a leading-edge real-time control prototypingsystem. Thanks to a new generation of extremely fast digital processors, the proposed system has the capability to process a much larger number of data in "real-time" than the system currently available to the applicants.This system will allow the applicants to tackle new and challenging research problems - such as the active control of noise in aircraft cabins generated by turbulent exterior airflow, active control of noise and vibration induced by helicopter drive train systems, active control of low frequency road noise inside automobiles or the synthesis of noise fields in aircraft cabins and cockpits for simulation purpose.
