Traditional loudspeaker equalization algorithms cannot decide the order of an equalizer before the whole equalization procedure has been completed. Designers have to try many times before they determine a proper order of the equalization filter. A method which solves this drawback is presented for loudspeaker equalization using balanced model truncation. The order of the equalizer can be easily decided using this algorithm and the error between the model and the loudspeaker can also be readily controlled. Examples are presented and the performance of the proposed method is discussed with comparative experiments.
传统的扬声器均衡算法在整个均衡过程完成之前无法确定均衡器的阶数。设计者在确定均衡滤波器的合适阶数之前必须进行多次尝试。本文提出了一种使用平衡模型截断来解决这一缺点的扬声器均衡方法。使用该算法可以轻松确定均衡器的阶数，并且模型与扬声器之间的误差也易于控制。文中给出了示例，并通过对比实验讨论了所提方法的性能。
