实验中采用加速度计和话筒作为传感器拾取板振动的加速度和闭空间内的声压信号，用压电陶瓷片作为振动控制源来控制混响声场通过简支矩形铝板向混凝土闭空间的声传入。

After that, the important equation for calculating reverberation time is given based on the definition of reverberation time and least squares method. Finally, we use our new method to calculate reverberation time in a rectangular enclosure; we also compare our results with those given by experiment and Sabine's equation. The comparison shows that the new method is more effective and accurate than Sabine's equation in calculating reverberation time of small enclosures.
