The property of the hybrid active silencer relies on the equivalent impedance at the secondary sound source position and the impedance distribution characteristics of the one-chamber pipe itself.

研究结果表明，复合有源消声器的消声效果取决于次级扬声器位置的等效声阻抗以及无源式消声管道本身的阻抗分布特性。

In this thesis, the study is focused on the characteristics of distributed sound source and its using in the active acoustical structure as the secondary source, including the foll.

本文为有源声学结构研究的一部分，侧重于研究分布式声源的声学特性，并对其作为次级源在有源声学结构中的应用进行了深入的研究。

It's not just the sound source that's on the loose either, as the companion active subwoofer uses a bespoke low-latency 2.4GHz connection (claimed to be 0.01 seconds delay) too -- no more hiding wires around the back.
