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.

在声学和振动中，有某些类型的问题需要强大的实时控制系统，能够处理大量输入和输出通道上的数据。这是主动控制问题（使用仔细调整的干扰来消除不必要的噪音或振动）和声场合成（我们试图在任意环境中使用一组再现扬声器物理地再现虚拟声场）的情况。这项由舍布鲁克大学声学小组（GAUS）的4名研究人员提交的提案旨在获得一个领先的实时控制原型系统。由于新一代极快的数字处理器，拟议的系统有能力“实时”处理比目前可供申请人使用的系统多得多的数据。此系统可让申请人处理新的及具挑战性的研究课题，例如主动控制飞机客舱内由外部湍流气流所产生的噪音、主动控制直升机传动系统所产生的噪音及振动、主动控制汽车内的低频道路噪音或合成飞机客舱及驾驶舱内的噪音场作模拟用途。
