查询词典 sound system

On the aspect of error compensation, the system using the geometric average sound pressure instead of the arithmetic average sound pressure to get the sound pressure of the measurement point. This method not only reduces the high frequency error in the sound intensity measurement, which compensates the finite difference approximation error, but also greatly reduces the computation of the sound pressure spectrum.

误差补偿方面，课题采用几何平均声压代替通常的算术平均声压来计算双传声器法的声场声压值，这样不仅可以有效的减少声强测量中的高频误差，对有限差分误差起到了补偿作用，而且还大大减小了声压谱计算中的计算量。

Experiments are carried out to give the transfer functions of each part in the ANC system, the spatial coherences of sound field and the Nyquist plots of the whole system. The results show that reverberant sound will also produce some unstable poles because of different time delays are needed in establishing normal mode response, but the gain margin is much greater than that for direct sound.

文章还从实验的角度，对ANC系统各个部分的传递函数、声场的空间相干性与系统的Nyquist图进行了分析，结果说明，混响声场的建立也需要一定的时间，所以混响声传播途径也将给系统带来一些不稳定的极点，但是它的增益裕量要比直达声途径大很多。
