| Abstract: | The principle that the sound field in auditorium is controlled by convolution is expounded, the design method of sound field control system is presented, and a real time sound field controlling system is constructed of a high speed DSP board, and the experimental results show that this method can increase the reverberation time at midfrequency more than three times with good effects. |
