Three control source structures for ventilation ducts are compared: directional source with single loudspeaker (proposed method); bidirectional source with single loudspeaker (existing method 1); directional source with a pair of loudspeakers (existing method 2). It has been shown based on a theoretical model that (i)larger phase lag in feedback path transfer function is achieved by using the existing method 2 compared with the existing method 1. Moreover, it has been shown based on a theoretical model and experimental results that (ii) the proposed method has the similar advantage to the existing method 2 with single loudspeaker.

比较了通风管道的三种控制源结构：单扬声器定向源（建议方法）、单扬声器双向源（现有方法1）和双扬声器定向源（现有方法2）。基于理论模型已经表明，（i）与现有方法1相比，通过使用现有方法2实现了更大的反馈路径传递函数的相位滞后。此外，基于理论模型和实验结果表明：（ii）所提出的方法具有与现有的单扬声器方法2相似的优点。
